Conservatives are a fascinating lot. Throughout the Cold War, they steadfastly maintained that the Cold War was necessary because communist tyrants were hell-bent on conquering the United States and subjugating the American people. That is, in fact, why the U.S. national-security establishment intervened in the Korean War and the Vietnam War and sacrificed more than 100,000 U.S. soldiers — supposedly to prevent the communists in North Korea and North Vietnam from ultimately coming to America and taking control of the United States.
The conservative mantra throughout the Cold War was encapsulated by the title of a book written in 1962 by a conservative curmudgeon named Fred Schwarz: You Can Trust the Communists (to be Communists.) The idea was that the communists were incorrigible liars who had one goal in mind: the defeat and Red takeover of the United States.
