Family background

The house in which Kim was born

Kim was born Kim Song Ju to father Kim Hyong Jik and mother Kang Pan Suk. Kim had two younger brothers, Kim Chul Ju and Kim Yong Ju.^[5]: 3 Kim Chul Ju died while fighting the Japanese and Kim Yong Ju was involved in the North Korean government and considered an heir to his brother before falling out of favor.^[6][7]

Kim's family, part of the Jeonju Kim clan, is said to have originated from Jeonju, North Jeolla Province. In 1860, his great-grandfather, Kim Ung-u, settled in the Mangyongdae neighborhood of Pyongyang. Kim was reportedly born in the small village of Mangyungbong (then called Namni) near Pyongyang on 15 April 1912.^[8][9]: 12 According to a 1964 semi-official biography of Kim, he was born in his mother's home in Chingjong, and later grew up in Mangyungbong.^[10]: 73

According to Kim, his family was always a step away from poverty. Kim said that he was raised in a very active Presbyterian Christian family. His maternal grandfather was a Protestant minister, and his father had gone to a missionary school and was an elder in the Presbyterian Church.^[11][12] According to an official North Korean government account, Kim's family participated in anti-Japanese activities and fled to Manchuria in 1920. Like most Korean families, they resented the Japanese occupation of the Korean peninsula (which had begun on 29 August 1910).^[9]: 12 Japanese repression of Korean opposition was harsh, resulting in the arrest and detention of more than 52,000 Korean citizens in 1912 alone.^[9]: 13 This repression had forced many Korean families to flee the Korean peninsula, and settle in Manchuria.^[13]

Nevertheless, Kim's parents, especially his mother, played a role in the anti-Japanese struggle that was sweeping the peninsula.^[9]: 16 Their exact involvement – whether their cause was missionary, nationalist, or both – is unclear.^[14]: 53

Communist and guerrilla activities

North Korean government sources credit Kim with founding the Down-with-Imperialism Union in 1926.^[15] He attended Whasung Military Academy in 1926, but found the academy's training methods outdated and quit it in 1927. He then attended Yuwen Middle School in China's Jilin province until 1930,^[16] when he rejected the feudal traditions of older-generation Koreans and became interested in communist ideologies. Seventeen-year-old Kim became the youngest member of the Korean Communist Youth Association, an underground Marxist organization with fewer than twenty members. It was led by Hŏ So (허소; 許笑), who belonged to the South Manchurian Communist Youth Association. The police discovered the group three weeks after it formed in 1929, and jailed Kim for several months. Kim's formal education ended after his arrest and imprisonment.^{[14]: 52 [5]: 7}

In 1931, Kim joined the Chinese Communist Party (CCP) – the Communist Party of Korea had been founded in 1925, but had been thrown out of the Communist International in the early 1930s for being too nationalist. He joined various anti-Japanese guerrilla groups in northern China. Feelings against the Japanese ran high in Manchuria, but as of May 1930 the Japanese had not yet occupied Manchuria. On 30 May 1930, a spontaneous violent uprising in eastern Manchuria arose in which peasants attacked some local villages in the name of resisting "Japanese aggression".^[17] The authorities easily suppressed this impromptu uprising. Because of the attack, the Japanese began to plan an occupation of Manchuria.^[18] In a speech Kim allegedly made before a meeting of Young Communist League delegates on 20 May 1931 in Yenchi County in Manchuria,^[19] he warned the delegates against such unplanned uprisings as the 30 May 1930 uprising in eastern Manchuria.^[20]

Four months later, on 18 September 1931, the "Mukden Incident" occurred, in which a relatively weak dynamite explosive charge went off near a Japanese railroad in the town of Mukden in Manchuria. Although no damage occurred, the Japanese used the incident as an excuse to send armed forces into Manchuria and to appoint a puppet government.^[21] In 1935, Kim became a member of the Northeast Anti-Japanese United Army, a guerrilla group led by the CCP.^[22] Kim was appointed the same year to serve as political commissar for the 3rd detachment of the second division, consisting of around 160 soldiers.^[14]: 53 Here Kim met the man who would become his mentor as a communist, Wei Zhengmin, Kim's immediate superior officer, who served at the time as chairman of the Political Committee of the Northeast Anti-Japanese United Army. Wei reported directly to Kang Sheng, a high-ranking party member close to Mao Zedong in Yan'an, until Wei's death on 8 March 1941.^{[5]: 8–10}

Kim's actions during the Minsaengdan incident helped solidify his leadership.^[23] The CCP operating in Manchuria had become suspicious that any Korean could secretly be a member of the pro-Japanese and anti-communist Minsaengdan.^[24] A purge resulted: over 1,000 Koreans were expelled from the CCP, including Kim (who was arrested in late 1933 and exonerated in early 1934), and 500 were killed.^[24] Kim Il Sung's memoirs – and those of the guerrillas who fought alongside him – cite Kim's seizing and burning the suspect files of the Purge Committee as key to solidifying his leadership.^[23] After the destruction of the suspect files and the rehabilitation of suspects, those who had fled the purge rallied around Kim.^[23] As historian Suzy Kim summarizes, Kim Il Sung "emerged from the purge as a definitive leader, not only for the bold move but also for his compassion."^[23]

In 1935, Kim took the name Kim Il Sung, meaning "Kim become the sun".^[25]: 30 Kim was appointed commander of the 6th division in 1937, at the age of 24, controlling a few hundred men in a group that came to be known as "Kim Il Sung's division". On June 4th 1937, he led 200 guerrillas in a raid on Poch'onbo, destroying the local government offices and setting fire to a Japanese police station and post office.^[26] The success of the raid demonstrated Kim's talents as a military leader.^[26] Even more significant than the military success itself was the political coordination and organization between the guerrillas and the Korean Fatherland Restoration Association, an anti-Japanese united front group based in Manchuria.^[26] These accomplishments would grant Kim some measure of fame among Chinese guerrillas, and North Korean biographies would later exploit it as a great victory for Korea.

For their part, the Japanese regarded Kim as one of the most effective and popular Korean guerrilla leaders ever.^{[27]: 160–161 [28]} He appeared on Japanese wanted lists as the "Tiger".^[29] The Japanese "Maeda Unit" was sent to hunt him in February 1940.^[29] Later in 1940, the Japanese kidnapped a woman named Kim Hye-sun, believed to have been Kim Il Sung's first wife. After using her as a hostage to try to convince the Korean guerrillas to surrender, she was killed. Kim was appointed commander of the 2nd operational region for the 1st Army, but by the end of 1940 he was the only 1st Army leader still alive. Pursued by Japanese troops, in late 1940, Kim and a dozen of his fighters escaped by crossing the Amur River into the Soviet Union.^{[14]: 53–54} Kim was sent to a camp at Vyatskoye near Khabarovsk, where the Soviets retrained the Korean communist guerrillas. In August 1942, Kim and his army were assigned to a special unit known as the 88th Separate Rifle Brigade, which belonged to the Soviet Red Army. Kim's immediate superior was Zhou Baozhong.^[30][31] Kim became a Major in the Soviet Red Army^[5]: 50 and served in it until the end of World War II in 1945.^[32]

Return to Korea

The Soviet Union declared war on Japan on 8 August 1945, and the Red Army entered Pyongyang on 24 August 1945. Stalin had instructed Lavrentiy Beria to recommend a communist leader for the Soviet-occupied territories and Beria met Kim several times before recommending him to Stalin.^[8][33][34]

Kim arrived in the Korean port of Wonsan on 19 September 1945 after 26 years in exile.^[25]: 51 According to Leonid Vassin, an officer with the Soviet MVD, Kim was essentially "created from zero". For one, his Korean was marginal at best; he only had eight years of formal education, all of it in Chinese. He needed considerable coaching to read a speech (which the MVD prepared for him) at a Communist Party congress three days after he arrived.^[35]: 50

In December 1945, the Soviets installed Kim as first secretary of the North Korean Branch Bureau of the Communist Party of Korea.^[25]: 56 Originally, the Soviets preferred Cho Man-sik to lead a popular front government, but Cho refused to support a UN-backed trusteeship and clashed with Kim.^[36] General Terentii Shtykov, who led the Soviet occupation of northern Korea, supported Kim over Pak Hon-yong to lead the Provisional People's Committee for North Korea on 8 February 1946.^[37] As chairman of the committee, Kim was "the top Korean administrative leader in the North," though he was still de facto subordinate to General Shtykov until the Chinese intervention in the Korean War.^{[34][25]: 56 [37]}

On 1 March 1946, while giving a speech to commemorate an anniversary of the March 1st Movement, a member of the anti-communist terrorist group the White Shirts Society attempted to assassinate Kim by lobbing a grenade at his podium. However, Soviet military officer Yakov Novichenko grabbed the grenade and absorbed the blast with his body, leaving Kim and other bystanders unharmed.^[38][39][40]

To solidify his control, Kim established the Korean People's Army (KPA), aligned with the Communist Party, and he recruited a cadre of guerrillas and former soldiers who had gained combat experience in battles against the Japanese and later against Nationalist Chinese troops.^[41] Using Soviet advisers and equipment, Kim constructed a large army skilled in infiltration tactics and guerrilla warfare. Prior to Kim's invasion of the South in 1950, which triggered the Korean War, Stalin equipped the KPA with modern, Soviet-built medium tanks, trucks, artillery, and small arms. Kim also formed an air force, equipped at first with Soviet-built propeller-driven fighters and attack aircraft. Later, North Korean pilot candidates were sent to the Soviet Union and China to train in MiG-15 jet aircraft at secret bases.^[42]

Claims that Kim Il Sung was an imposter

Several sources claim the name "Kim Il Sung" had previously been used by a prominent early leader of the Korean resistance, Kim Kyung-cheon.^[35]: 44 The Soviet officer Grigory Mekler, who worked with Kim during the Soviet occupation, said that Kim took this name from a former commander who had died.^[43] However, historian Andrei Lankov has argued that this is unlikely to be true. Several witnesses knew Kim before and after his time in the Soviet Union, including his superior, Zhou Baozhong, who dismissed the claim of a "second" Kim in his diaries.^[14]: 55 Historian Bruce Cumings pointed out that Japanese officers from the Kwantung Army have attested to his fame as a resistance figure.^{[27]: 160–161}

According to the 2019 book Surprise, Kill, Vanish by investigative journalist Annie Jacobsen, the United States Central Intelligence Agency (CIA) once concluded that Kim Il Sung was a blackmailed imposter operated by the Soviet Union.^[44] The dossier titled "The Identity of Kim Il Sung" ascribed the leader's true identity to Kim Song-ju, an orphaned child caught stealing money from a classmate who killed his classmate to avoid embarrassment. The dossier alleges Soviet intelligence officers identified the opportunity to blackmail Kim Song-ju into leading the North Korean Communist Party as a Soviet puppet under the name of the real war hero Kim-Il Sung, whom Stalin had disappeared. Jacobsen also writes that the CIA learned "specific instructions [were] given to the leaders of the regime that there should be no questions raised about Kim [Il Sung]'s identity."^[44]

Historians generally accept the view that, while Kim's exploits were exaggerated by the personality cult which was built around him, he was a significant guerrilla leader.^[45][46][47]

Early years

Kim's official portrait in 1948

Despite the United Nations' plans to conduct nationwide elections in Korea, on 15 August 1948, the US-occupied south proclaimed the Republic of Korea, which claimed sovereignty over all of Korea. In response, the Soviets held elections of their own in their northern occupation zone on 25 August 1948 for a Supreme People's Assembly.^[48] Voters were presented with a single list from the Communist-dominated Democratic Front for the Reunification of the Fatherland. The Democratic People's Republic of Korea was proclaimed on 9 September 1948, with Kim as the Soviet-designated premier.

On 12 October, the Soviet Union recognized Kim's government as the sovereign government of the entire peninsula, including the south.^[49] The Communist Party merged with the New People's Party of Korea to form the Workers' Party of North Korea, with Kim as vice-chairman. In 1949, the Workers' Party of North Korea merged with its southern counterpart to become the Workers' Party of Korea (WPK) with Kim as party chairman.^[50] By 1949, Kim and the communists had consolidated their rule in North Korea.^[35]: 53 Around this time, Kim began promoting an intense personality cult. The first of many statues of him appeared, and he began calling himself "Great Leader".^[35]: 53

In February 1946, Kim Il Sung decided to introduce a number of reforms. Over 50% of the arable land was redistributed, an 8-hour work day was proclaimed and all heavy industry was to be nationalized.^[5]: 68 There were improvements in the health of the population after he nationalized healthcare and made it available to all citizens.^[51]

Korean War

Kim signs the Korean Armistice Agreement

Archival material suggests^[52][53][54] that North Korea's decision to invade South Korea was Kim's initiative, not a Soviet one. Evidence suggests that Soviet intelligence, through its espionage sources in the US government and British SIS, had obtained information on the limitations of US atomic bomb stockpiles as well as defense program cuts, leading Stalin to conclude that the Truman administration would not intervene in Korea.^[55]

China acquiesced only reluctantly to the idea of Korean reunification after being told by Kim that Stalin had approved the action.^[52][53][54] The Chinese did not provide North Korea with direct military support (other than logistics channels) until United Nations troops, largely US forces, had nearly reached the Yalu River late in 1950. At the outset of the war in June and July, North Korean forces captured Seoul and occupied most of the South, save for a small section of territory in the southeast region of the South that was called the Pusan Perimeter. But in September, the North Koreans were driven back by the US-led counterattack that started with the UN landing in Incheon, followed by a combined South Korean-US-UN offensive from the Pusan Perimeter. By October, UN forces had retaken Seoul and invaded the North to reunify the country under the South. On 19 October, US and South Korean troops captured P'yŏngyang, forcing Kim and his government to flee north, first to Sinuiju and eventually into Kanggye.^[56][57]

On 25 October 1950, after sending various warnings of their intent to intervene if UN forces did not halt their advance,^[58]: 23 Chinese troops in the thousands crossed the Yalu River and entered the war as allies of the KPA. There were nevertheless tensions between Kim and the Chinese government. Kim had been warned of the likelihood of an amphibious landing at Incheon, which was ignored. There was also a sense that the North Koreans had paid little in war compared to the Chinese who had fought for their country for decades against foes with better technology.^{[58]: 335–336} The UN troops were forced to withdraw and Chinese troops retook P'yŏngyang in December and Seoul in January 1951. In March, UN forces began a new offensive, retaking Seoul and advanced north once again halting at a point just north of the 38th Parallel. After a series of offensives and counter-offensives by both sides, followed by a grueling period of largely static trench warfare that lasted from the summer of 1951 to July 1953, the front was stabilized along what eventually became the permanent "Armistice Line" of 27 July 1953. Over 2.5 million people died during the Korean War.^[59]

Chinese and Russian documents from that time reveal that Kim became increasingly desperate to establish a truce, since the likelihood that further fighting would successfully unify Korea under his rule became more remote with the UN and US presence. Kim also resented the Chinese taking over the majority of the fighting in his country, with Chinese forces stationed at the center of the front line, and the Korean People's Army being mostly restricted to the coastal flanks of the front.^[60]

Consolidating power

With the end of the Korean War, despite the failure to unify Korea under his rule, Kim Il Sung proclaimed the war a victory in the sense that he had remained in power in the north. However, the three-year war left North Korea devastated, and Kim immediately embarked on a large reconstruction effort. He launched a five-year national economic plan (akin to Soviet Union's five-year plans) to establish a command economy, with all industry owned by the state and all agriculture collectivized. The economy was focused on heavy industry and arms production. By the 1960s, North Korea enjoyed a standard of living higher than the South, which was fraught with political instability and economic crises.^[61][62][63]

In the ensuing years, Kim established himself as an independent leader of international communism. In 1956, he joined Mao in the "anti-revisionist" camp, which did not accept Nikita Khrushchev's program of de-Stalinization, yet he did not become a Maoist himself. At the same time, he consolidated his power over the Korean communist movement. Rival leaders were eliminated. Pak Hon-yong, leader of the Korean Communist Party, was purged and executed in 1955. Choe Chang-ik appears to have been purged as well.^[64][65] Yi Sang-Cho, North Korea's ambassador to the Soviet Union and a critic of Kim who defected to the Soviet Union in 1956, was declared a factionalist and a traitor.^[66] The 1955 Juche speech, which stressed Korean independence, debuted in the context of Kim's power struggle against leaders such as Pak, who had Soviet backing. This was little noticed at the time until state media started talking about it in 1963.^[67][68] Kim developed the policy and ideology of Juche in opposition to the idea of North Korea as a satellite state of China or the Soviet Union.

Kim transformed North Korea into what Wonjun Song and Joseph Wright consider a personalist dictatorship, where power was centralized in Kim personally.^[69] Kim Il Sung's cult of personality had initially been criticized by some members of the government. The North Korean ambassador to the USSR, Li Sangjo, a member of the Yan'an faction, reported that it had become a criminal offense to so much as write on Kim's picture in a newspaper and that he had been elevated to the status of Marx, Lenin, Mao, and Stalin in the communist pantheon. He also charged Kim with rewriting history so it would appear as if his guerrilla faction had single-handedly liberated Korea from the Japanese, completely ignoring the assistance of the Chinese People's Volunteers. In addition, Li stated that in the process of agricultural collectivization, grain was being forcibly confiscated from the peasants, leading to "at least 300 suicides" and he also stated that Kim made nearly all major policy decisions and appointments himself. Li reported that over 30,000 people were in prison for completely unjust and arbitrary reasons which were as trivial as not printing Kim Il Sung's portrait on sufficient quality paper or using newspapers with his picture to wrap parcels. Grain confiscation and tax collection were also conducted with force, which consisted of violence, beatings, and threats of imprisonment.^[70]

During the 1956 August Faction Incident, Kim Il Sung successfully resisted Soviet and Chinese efforts to depose him in favor of pro-Soviet Koreans or Koreans who belonged to the pro-Chinese Yan'an faction.^[71][72] The last Chinese troops withdrew from the country in October 1958, which is the consensus as the latest date when North Korea became effectively independent, though some scholars believe that the 1956 August incident demonstrated North Korea's independence.^[71][72]

During his rise and consolidation of power, Kim created the songbun caste system, which divided the North Korean people into three groups. Each person was classified as belonging to the "core", "wavering", or "hostile" class, based on his or her political, social, and economic background – a system which persists today. Songbun was used to decide all aspects of a person's existence in North Korean society, including access to education, housing, employment, food rationing, ability to join the ruling party, and even where a person was allowed to live. Large numbers of people from the so-called hostile class, which included intellectuals, land owners, and former supporters of Japan's occupying government during World War II, were forcibly relocated to the country's isolated and impoverished northern provinces. When years of famine ravaged the country in the 1990s, those people who lived in its marginalized and remote communities were hardest hit.^[73]

During his rule, North Korea was responsible for widespread human rights abuses.^[74][75][76] Kim Il Sung punished real and perceived dissent through purges which included public executions and enforced disappearances. Not only dissenters but their entire extended families were reduced to the lowest songbun rank, and many of them were relocated to a secret system of political prison camps. These camps or kwanliso, a part of Kim's vast network of abusive penal and forced labor institutions, were fenced and heavily guarded colonies in mountainous areas of the country, where prisoners were forced to perform back-breaking labor such as logging, mining, and picking crops. Most prisoners were held in these camps for life, and their living and working conditions in them were often deadly. For example, prisoners were nearly starved to death, denied medical care, denied proper housing and clothes, subjected to sexual violence, regularly mistreated, tortured and executed by guards.^[73]

Later years

Kim and Romanian president Nicolae Ceauşescu at Moranbong Stadium, 1978

Despite his opposition to de-Stalinization, Kim never officially severed relations with the Soviet Union, and he did not take part in the Sino-Soviet Split. After Khrushchev was replaced by Leonid Brezhnev in 1964, Kim's relations with the Soviet Union became closer. At the same time, Kim was increasingly alienated by Mao's unstable style of leadership, especially during the Cultural Revolution in the late 1960s. Kim in turn was denounced by Mao's Red Guards.^[77] At the same time, Kim reinstated relations with most of Eastern Europe's communist countries, primarily with Erich Honecker's East Germany and Nicolae Ceaușescu's Romania. Ceauşescu was heavily influenced by Kim's ideology, and the personality cult which grew around him in Romania was very similar to that of Kim.^[78]

In the 1960s, Kim became impressed with the efforts of North Vietnamese Leader Ho Chi Minh to reunify Vietnam through guerrilla warfare and thought that something similar might be possible in Korea.^{[79]: 30–31} Infiltration and subversion efforts were thus greatly stepped up against US forces and the leadership in South Korea.^{[79]: 32–33} These efforts culminated in an attempt to storm the Blue House and assassinate President Park Chung Hee.^[79]: 32 North Korean troops thus took a much more aggressive stance toward US forces in and around South Korea, engaging US Army troops in fire-fights along the Demilitarized Zone. The 1968 capture of the crew of the spy ship USS Pueblo was a part of this campaign.^[79]: 33

Albania's Enver Hoxha (another independent-minded communist leader) was a fierce enemy of the country and Kim Il Sung, writing in June 1977 that "genuine Marxist-Leninists" will understand that the "ideology which is guiding the Korean Workers' Party and the Communist Party of China ... is revisionist" and later that month he added that "in Pyongyang, I believe that even Tito will be astonished at the proportions of the cult of his host [Kim Il sung], which has reached a level unheard of anywhere else, either in past or present times, let alone in a country which calls itself socialist."^[80][81] He further claimed that "the leadership of the Communist Party of China has betrayed [the working people]. In Korea, too, we can say that the leadership of the Korean Workers' Party is wallowing in the same waters" and claimed that Kim Il Sung was begging for aid from other countries, especially among the Eastern Bloc and non-aligned countries like Yugoslavia. As a result, relations between North Korea and Albania would remain cold and tense right up until Hoxha's death in 1985.

Although a resolute anti-communist, Zaire's Mobutu Sese Seko was also heavily influenced by Kim's style of rule.^[82]

The North Korean government's practice of abducting foreign nationals, such as South Koreans, Japanese, Chinese, Thais, and Romanians, is another practice of Kim Il Sung which persists to the present day. Kim Il Sung planned these operations to seize persons who could be used to support North Korea's overseas intelligence operations, or those who had technical skills to maintain the socialist state's economic infrastructure in farms, construction, hospitals, and heavy industry. According to the Korean War Abductees Family Union (KWAFU), those abducted by North Korea after the war included 2,919 civil servants, 1,613 police, 190 judicial officers and lawyers, and 424 medical practitioners. In the hijacking and seizure of Korean Airlines flight YS-11 in 1969 by North Korean agents, the pilots and mechanics, and others with specialized skills, were the only ones never permitted to return to South Korea. The total number of foreign abductees and disappeared is still unknown but is estimated to include more than 200,000 people. The vast majority of disappearances occurred or were linked to the Korean War, but hundreds of South Koreans and Japanese people were abducted between the 1960s and 1980s. A number of South Koreans and nationals of the People's Republic of China have also been apparently abducted in the 2000s and 2010s. At least 100,000 people remain disappeared.^[73]

The Constitution of North Korea was proclaimed on December 27, 1972, which created the position of the President of North Korea. Kim gave up his former Premier of the Cabinet position, which he had held since 1948, and became instead president, after the 1972 North Korean parliamentary election. On 14 April 1975, North Korea discontinued most formal use of its traditional units and adopted the metric system.^[83] In 1980, he decided that his son Kim Jong Il would succeed him, and increasingly delegated the running of the government to him. The Kim family was supported by the army, due to Kim Il Sung's revolutionary record and the support of the veteran defense minister, O Chin-u. At the Sixth Party Congress in October 1980, Kim publicly designated his son as his successor. In 1986, a rumor spread that Kim had been assassinated, making the concern for Jong-il's ability to succeed his father actual. Kim dispelled the rumors, however, by making a series of public appearances. It has been argued, however, that the incident helped establish the order of succession – the first apparent patrilineal in a communist state – which eventually would occur upon Kim Il Sung's death in 1994.^[84]

From about this time, North Korea encountered increasing economic difficulties. South Korea became an economic powerhouse fueled by Japanese and American investment, military aid, and internal economic development, while North Korea stagnated and then declined in the 1980s.^[85][86] The practical effect of Juche was to cut the country off from virtually all foreign trade in order to make it entirely self-reliant. The economic reforms of Deng Xiaoping in China from 1979 onward meant that trade with the moribund economy of North Korea held decreasing interest for China. The Revolutions of 1989 in Eastern Europe and the dissolution of the Soviet Union, from 1989 to 1992, completed North Korea's virtual isolation. These events led to mounting economic difficulties because Kim refused to issue any economic or political reforms.^[87]

Kim's calcium deposit tumor is noticeable on the back of his head in this rare newsreel still image during a diplomatic meeting between him and Chinese Communist Party Chairman Mao Zedong in Beijing, 1970.

As he aged, starting in the 1970s, Kim developed a calcium deposit growth on the right side of the back of his neck. It was long believed that its close proximity to his brain and spinal cord made it inoperable. However, Juan Reynaldo Sanchez, a defected bodyguard for Fidel Castro who met Kim in 1986 wrote later that it was Kim's own paranoia that prevented it from being operated on.^[88] Because of its unappealing nature, North Korean reporters and photographers were required to photograph Kim while standing slightly to his left in order to hide the growth from official photographs and newsreels. Hiding the growth became increasingly difficult as the growth reached the size of a baseball by the late 1980s.^[89]: xii

Kim Il Sung's 80th birthday ceremony with international guests, April 1992

To ensure a full succession of leadership to his son and designated successor Kim Jong Il, Kim turned over his chairmanship of North Korea's National Defense Commission – the body mainly responsible for control of the armed forces as well as the supreme commandership of the country's now million-man strong military force, the Korean People's Army – to his son in 1991 and 1993. So far, the elder Kim – even though he is dead – has remained the country's president and the chairman of the Party's Central Military Commission, the party's organization that has supreme supervision and authority over military matters.

In early 1994, Kim began investing in nuclear power to offset energy shortages brought on by economic problems. This was the first of many "nuclear crises". On 19 May 1994, Kim ordered spent fuel to be unloaded from the already disputed nuclear research facility in Yongbyon. Despite repeated chiding from Western nations, Kim continued to conduct nuclear research and carry on with the uranium enrichment program. In June 1994, former US President Jimmy Carter traveled to Pyongyang in an effort to persuade Kim to negotiate with the Clinton administration over its nuclear program.^[90] To the astonishment of the United States and the International Atomic Energy Agency, Kim agreed to halt his nuclear research program and seemed to be embarking upon a new opening to the West.^[91]

On the late morning shortly before 12:00 noon on 7 July 1994, Kim Il Sung collapsed from a sudden heart attack at his residence in Hyangsan, North Pyongan. After the heart attack, Kim Jong Il ordered the team of doctors who were constantly at his father's side to leave and arranged for the country's best doctors to be flown in from Pyongyang. After several hours, the doctors from Pyongyang arrived, but despite their efforts to save him, Kim Il Sung died at 02:00 PST on 8 July 1994, aged 82.^[92] After the traditional Confucian mourning period, his death was declared 34 hours later.^[93]

Kim Il Sung's death resulted in nationwide mourning and a ten-day mourning period was declared by Kim Jong Il. His funeral was scheduled to be held on 17 July 1994 in Pyongyang but was delayed until 19 July.^[94] It was attended by hundreds of thousands of people who were flown into the city from all over North Korea. Kim Il Sung's body was placed in a public mausoleum at the Kumsusan Palace of the Sun, where his preserved and embalmed body lies under a glass coffin for viewing purposes. His head rests on a traditional Korean pillow and he is covered by the flag of the Workers' Party of Korea. Newsreel video of the funeral at Pyongyang was broadcast on several networks and can now be found on various websites.^[95]
