"Stalin and his successors were content with the Cold War because war scares and the alleged threat of capitalistic attack enabled the Politburo to maintain unity and prevent any threat of civil war in Soviet Russia, despite much slave labor and low living standards. . . .
The antagonism of the Western Powers and the Korean War aided [the Chinese Communists] in instituting a reign of terror at home and eliminating their enemies under the guise of the needs of defense and national security."
