Michael Gerson, noting that Democrats in a rush to get out of Iraq offer no plan to deal with the chaos that would result down the road, offers a painful reminder in his article, An Exit to Disaster.
In 1974, a weary Congress cut off funds for Cambodia and South Vietnam, leading to the swift fall of both allies. In his memoir, "Years of Renewal," Henry Kissinger tells the story of former Cambodian prime minister Sirik Matak, who refused to leave his country.
"I thank you very sincerely," Matak wrote in response, "for your offer to transport me towards freedom. I cannot, alas, leave in such a cowardly fashion. As for you, and in particular for your great country, I never believed for a moment that you would have this sentiment of abandoning a people which has chosen liberty. You have refused us your protection, and we can do nothing about it. You leave, and my wish is that you and your country will find happiness under this sky. But, mark it well, that if I shall die here on the spot and in my country that I love, it is no matter, because we are all born and must die. I have only committed this mistake of believing in you [the Americans]."
Eventually, between 1 million and 2 million Cambodians were murdered by the Khmer Rouge when "peace" came to Indochina. Matak, Kissinger recounts, was shot in the stomach and died three days later.
