As is widely known, in 1975, the United States abandoned the government of Cambodian prime minister Lon Nol and the Khmer Rouge took power. What is less known is that at the time, then-freshman senator Joseph Biden supported the evacuation of the Americans from Vietnam and Cambodia.
On April 25, 1975, the Americans exited Cambodia. Former prime minister Sirik Matak Sisowath, who refused to leave and was killed by the Khmer Rouge days later, famously remarked: “I have only committed the mistake of believing in you [the Americans].”
While critics have said that now-President Biden’s recent Afghanistan policy was ad hoc and not well thought out, it is much the same as what his approach to Cambodia was in the 1970s.
