In the book Brother Enemy: The War After the War, Nayan Chanda describes his experience of witnessing the victories of communists in South East Asia and the United States military involvement in this region following these events. By which, the fall of Saigon on April 30th, 1975 was not only the marching and fighting of the North Vietnamese Army and Vietcong into the capital of the Republic of Vietnam, but also the attempt of escaping of many south Vietnamese people and the American effort of evacuating their citizens and friends out of the country. After the lose of Vietnam, American marks their turn back in this region by the attack on Khmer Rouge to rescue the Mayaguez, an old American container ship. This event is the usual American behavior after losing the war. For instance, during the Korean War, after the United Nations forces, with the United States as the principal force, was pushed back by the Chinese army, American General Douglas MacArthur wants to save the US victory by requesting the nuclear bombs from President Harry Truman. These actions prove that American military proud was bigger than anything so that they are ready to take any action to secure it.
