JAKARTA, Indonesia (AP) — Declassified files have revealed new details of U.S. government knowledge and support of an Indonesian army extermination campaign that killed several hundred thousand civilians during anti-communist hysteria in the mid-1960s.
The thousands of files from the U.S. Embassy in Jakarta covering 1963-66 were made public Tuesday after a declassification review that began under the Obama administration. The Associated Press reviewed key documents in the collection in advance of their release.
The files fill out the picture of a devastating reign of terror by the Indonesian army and Muslim groups that has been sketched by historians and in a U.S. State Department volume that was declassified in 2001 despite a last-minute CIA effort to block its distribution.
In 1965, Indonesia had the world's third-largest communist party after China and the Soviet Union, with several million members, and the country's president, the charismatic Sukarno, was vociferously socialist and anti-American.
U.S. officials despaired of Indonesia's apparently unstoppable drift into the communist fold and were ecstatic when conservative generals imposed martial law in Jakarta, seized state radio and set out to annihilate the country's communist party on the pretext that it had tried to overthrow the government. Within months, the army would prevail in its power struggle with Sukarno, shifting Indonesia's political orientation to the U.S. and opening its huge market to American companies.
The newly released files underline the U.S. Embassy's and State Department's early, detailed and ongoing knowledge of the killings and eagerness to avoid doing anything that would hinder the Indonesian army. Historians had already established that the U.S. provided lists of senior communist party officials, radio equipment and money as part of active support for the army.
The documents also show that U.S. officials had credible information that contradicted the Indonesian army's lurid story that the kidnapping and killing of seven generals in an abortive coup by junior officers on Sept. 30, 1965, which paved the way for the bloodbath, was ordered by the Indonesian communist party and Beijing.
The documents specifically mention mass killings ordered by Suharto, a general who within months would seize total power and rule Indonesia for more than three decades, and the pivotal role in carrying out the massacres by groups that today remain Indonesia's biggest mainstream Muslim organizations: Nahdlatul Ulama, its youth wing Ansor and Muhammadiyah.
A Dec. 21, 1965, cable from the embassy's first secretary, Mary Vance Trent, to the State Department referred to events as a "fantastic switch which has occurred over 10 short weeks." It also included an estimate that 100,000 people had been slaughtered.
In Bali alone, some 10,000 people had been killed by mid-December, including the parents and distant relatives of the island's pro-communist governor, and the slaughter was continuing, the cable said. Two months later, another embassy cable cited estimates that the killings in Bali had swelled to 80,000.
A cable that was part of the 2001 State Department volume showed that by April 1966, the embassy was staggered by the scale of the murders and acknowledged, "We frankly do not know whether the real figure is closer to 100,000 or 1,000,000." Even the Indonesian government had only a "vague idea" of the true number, the cable said.
The release of the documents coincides with an upsurge in anti-communist rhetoric in Indonesia, where communism remains a frequently invoked boogeyman for conservatives despite the collapse of the Soviet Union nearly three decades ago and China's embrace of global capitalism.
Discussion of the 1965-66 period that departs from the Suharto era's partly fictional account of a heroic national uprising against communism is still discouraged. A landmark symposium last year that brought together aging survivors of the bloodbath and government ministers sparked a furious backlash. And last month, an anti-communist mob led by retired generals attacked a building in central Jakarta where activists had planned to discuss the killings.
"The mass killings of 1965-66 are among the world's worst crimes against humanity, and our country's darkest secret," said Veronica Koman, an Indonesian human rights lawyer. "The 1965-66 survivors are all very old now, and I'm afraid that they will not see justice before they die. Hopefully with these cables coming to light, the truth can emerge and perpetrators can be held accountable."
U.S. Senator Tom Udall, who in 2015 introduced a resolution in the Senate urging Indonesia's government to create a truth and reconciliation commission, said the U.S. must also confront its role in these "terrible acts."
Indonesia's Muslim mass organizations are among those reluctant to face scrutiny for their role, which in the fevered atmosphere of 1965 was characterized by Islamic leaders as a holy war against atheists.
Under the direction of the army, the Muslim organizations Nahdlatul Ulama and Muhammadiyah were enthusiastic participants in mass murder, carrying out indiscriminate killings as well as organized executions, according to the documents. They also mention the army's recruiting of Catholics to help with its extermination campaign in central Java.
A December 1965 cable from the U.S. Consulate in Medan, Indonesia, reported that preachers in Muhammadiyah mosques were telling congregations that all who joined the communist party must be killed, saying they are the "lowest order of infidel, the shedding of whose blood is comparable to killing chicken."
A detailed four-page report covering mid- to late November 1965 by the U.S. Embassy's political affairs officer, Edward E. Masters, discussed the spread of mass executions to several provinces and the role of youth groups in helping to solve the "main problem" of where to house and what to feed PKI prisoners. PKI is the Indonesian acronym for the country's communist party.
"Many provinces appear to be successfully meeting this problem by executing their PKI prisoners, or killing them before they are captured, a task in which Moslem youth groups are providing assistance," the report said. A cable from earlier in the month mentions an estimated 62,000 prisoners in the province of Central Java alone.
Ansor, the youth arm of Nahdlatul Ulama, was responsible for "brutal attacks" on communists, according to a Dec. 10, 1965, cable, but also caused problems by doing the same to non-communists involved in personal feuds with its members.
Possibly the earliest mention of systematic bloodshed in cables to Washington is a mid-October 1965 record of conversations between the embassy's second secretary and Bujung Nasution, a special assistant to Indonesia's attorney general involved with intelligence matters. Like other intermediaries of the Indonesian army and its allies sent to approach the embassy, Nasution was apparently trying to assess whether the U.S. would object to the extermination campaign.
According to Nasution, the army had already executed many cadres, but this information, he said, must be closely held because the army needed more time to break the communists.
The memo described Nasution as alarmed that reports of atrocities had been leaked to the Malaysian press. It said he warned that it was critical that Sukarno did not learn of the extent of the army's repression, especially from the foreign media.
In response, the second secretary, Robert G. Rich, reassured Nasution.
The U.S. government was fully aware of the sensitive nature of the current events, said Rich, and was "making every effort to avoid stimulating press speculation."
