killed, and hand these names over to the army and then check off which ones had been killed. They would get the list back with the names ticked off [designating] who had been captured and killed. Regarding the 5,000 individuals named on the lists, Oppenheimer contends "my understanding is that 100% were killed." Robinson also asserts that "despite Marten's later denials of any such intent, these actions almost certainly aided in the death or detention of many innocent people," and that providing the lists "sent a powerful message that the US government agreed with and supported the army's campaign against the PKI, even as that campaign took its terrible toll in human lives." Writing in his 2020 book The Jakarta Method, Vincent Bevins says that this was not the first instance of US officials providing kill lists of suspected communists to members of foreign regimes, as they had done so in Guatemala in 1954 and Iraq in 1963. Bevins also notes that it wasn't a practice of US government officials alone, as managers of US-owned plantations also provided the Indonesian army with lists of "troublesome" communists and union organizers who were subsequently rounded up and murdered. On December 10, 2014, Senator Tom Udall (D-NM) introduced a "Sense of the Senate Resolution" which condemned the killings and called for the declassification of all documents pertaining to U.S. involvement in the events, noting that "the U.S. provided financial and military assistance during this time and later, according to documents released by the State Department." In 2016, Indonesia's human rights commission submitted an official request to the U.S. government to declassify archived files believed to detail the CIA's involvement in the killings. A tribunal on the mass killings held in The Hague concluded the killings constitute crimes against humanity, and that the United States and other Western governments were complicit in the crimes. On October 17, 2017, declassified documents from the US embassy in Jakarta covering 1963-66 revealed that not only did the US government have detailed knowledge of the killings as they happened (and welcomed them), but also had actively encouraged and facilitated the massacres to further their geopolitical interests in the region. A November 1965 report by the aforementioned political affairs officer, Edward E Masters, examined the spread of large scale executions to multiple provinces and the role of youth groups in helping resolve the "main problem" of housing and feeding
