On April 30, North Vietnamese army tanks crashed through the gates of the presidential palace in Saigon, emphatically punctuating the end of the nation’s three-decade civil war. Led by the charismatic Ho Chi Minh, the struggle had been launched at the end of World War II as a rebellion against French colonial rule. At first Ho’s rebel group, the Vietminh, had harbored no strong ideological leanings except an overwhelming thirst for independence. Ho even made serious overtures toward obtaining American support. When they failed, though, he turned to China and the Soviet Union, and the results bore out the proverb “Who would sup with the devil must have a long spoon.” What had been a fluid political situation soon froze in the deep chill of the Cold War, and the insurrection turned into a protracted conflict between the communist-backed North and the capitalist-backed South—a proxy fight of the sort that would plague the world for nearly half a century.
