Background on Sukarno(I didn't know anything on this guy either so I looked it up) The son of a
Javanese nobleman and his Balinese wife from Buleleng regency, Sukarno was born in Surabaya (although several sources said he was born in Blitar, East Java) in the Dutch East Indies (now Indonesia). He was admitted into a Dutch-run school as a child. When his father sent him to Surabaya in 1916 to attend a secondary school, he met Tjokroaminoto, a future nationalist. In 1921 he began to study at the Technische Hoogeschool in Bandung.
Sukarno was fluent in several languages, especially Dutch. He once remarked that when he was studying in Surabaya, he often sat behind the screen in movie theaters reading the Dutch subtitles in reverse, because he could not afford the regular front seating's price.
Sukarno became a leader of an Indonesian independence movement party, Partai Nasional Indonesia when it was founded in 1927. He also promoted his belief that Japan would commence a war against the imperialist Western powers and that
Java could then gain its independence with Japan's aid. He was arrested in 1929 by Dutch colonial authorities and sentenced to two years in prison. By the time he was released, he had become a popular hero. In the 1930s he was again arrested several times and was in jail when Japan occupied the archipelago in 1942.
During World War II, indigenous forces across both Sumatra and Java aided the Japanese against the Dutch, but would not cooperate in the supply of the aviation fuel which was essential for the Japanese war effort. Desperate for local support in supplying the volatile cargo, Japan now brought Sukarno back to Jakarta.
Sukarno refused to ever talk about his actions during the war. However, several historians noted that he helped the Japanese in obtaining its aviation fuel as well as Romusha (volunteer work units) and Peta and Heiho (Javanese volunteer army troops) by use of Sukarno's speech broadcast on the Japanese radio and loud speaker networks across Java. By mid-1945 these units numbered around two million, and were preparing to defeat any Allied forces sent to re-take Java.
On November 10, 1943 Sukarno was decorated by the Emperor of Japan in Tokyo. He also became head of Badan Penyelidik Usaha Persiapan Kemerdekaan Indonesia (BPUPKI), the Japanese-organized committee through which Indonesian independence was later gained.
Following the Japanese surrender, Sukarno, Mohammad Hatta, and Radjiman Wediodiningrat were summoned by Marshal Terauchi, Commander-in-Chief of Japan's Southern Expeditionary Forces in Saigon. Sukarno initially hesitated in declaring Indonesia's independence. He and Mohammad Hatta were kidnapped by Indonesian youth groups to Rengasdengklok, west of Jakarta. Finally Sukarno and Mohammad Hatta declared the Republic of Indonesia in August 17, 1945.
Sukarno's vision for the 1945 Indonesian constitution comprised the Panca Sila. (Sanskrit - five pillars). Sukarno's political philosophy was guided by (in no particular order) elements of Marxism, nationalism and Islam. This is reflected in the Panca Sila, in the order in which he originally espoused them in a speech on June 1, 19451:
Nationalism (as in national unity)
Internationalism (one nation sovereign amongst equals)
Representative Democracy (all significant groups represented)
Social Justice (Marxist influenced)
Belief in God (with a secular government however)
The Indonesian parliament, founded on the basis of this original (and subsequent revised) constitutions, proved all but ungovernable. This was due to irreconcilable differences between various social, political, religious and ethnic factions2.
Sukarno's government initially refused to form a national army, for fear of antagonizing the Allied forces and their doubt in whether they will be able to form an adequate military apparatus. The various militia groups at that time were encouraged to join the BKR -- Badan Keamanan Rakyat (The People's Security Organization) -- itself a subordinate of the "War Victims Assistance Organization". It was only in October 1945 that the BKR was reformed into the TKR -- Tentara Kemanan Rakyat (The People's Security Army) in response to increasing Dutch presence in Indonesia. In the ensuing chaos between various factions and Dutch attempts to re-establish colonial control, Dutch troops captured Sukarno in December 1948, but were forced to release him after the ceasefire. He returned to Jakarta in December 28, 1949.
Sukarno's government was not universally accepted in Indonesia. Indeed, many factions and regions attempted to separate themselves from his govenment, and there were several internal conflicts even during the period of armed insurgency against the Dutch. One such example is the Leftist-backed seccessionist attempt by elements of the military in Madiun, East Java in 1948, in which many accused supporters of the separatists were allegedly executed.
There were further attempts of military coups against Sukarno in 1956, including the well-publicized separatist movement in Sulawesi supported by the CIA, during which conflict an American aviator operating in support of the separatists was shot down and captured.
In an effort to restore order, Sukarno established what he called guided democracy, in which he wielded progressively more executive powers, whilst maintaining a multiparty parliament.
You can read more on Wikipedia. It seems he started off as a ok guy but gradual drifted towards the dark side and eventually became a dictator as time went on(sounds like the plot of the Star Wars prequels..

). This pathed the way for one of his generals(the Hitler of Indonesia) to overthrow Sukarno and place himself in charge.
Suharto then organized anti-communist purges(and outright genocide) which may have been actually launched by the US government itself....
An official CIA report called the purge "one of the worst mass murders of the 20th century."2 American diplomats 25 years later revealed that they had compiled lists of Indonesian "communist operatives" and had turned over as many as 5,000 names to the Indonesian military. Robert Martens, former member of the US political embassy in Jakarta said in 1990: "It really was a big help to the army. They probably killed a lot of people, and I probably have a lot of blood on my hands, but that's not all bad. There's a time when you have to strike hard at a decisive moment." Howard Fenderspiel, the Indonesia expert at the State Department's Bureau of Intelligence and Research in 1965: "No one cared, as long as they were communists, that they were being butchered. No one was getting very worked up about it"3
