In a 1965 speech at Johns Hopkins University, President Lyndon Johnson said, "Over this war—and all Asia—is another reality: the
deepening shadow of Communist China. . . . This is a regime which has destroyed freedom in Tibet, which has attacked India, and has been condemned by the United Nations for aggression in Korea.
