With the rejuvenated nationalist movements in wait, the Europeans returned to a very different Southeast Asia after World War II. Indonesia declared independence on 17 August 1945 and subsequently fought a bitter war against the returning Dutch; the Philippines was granted independence by the United States in 1946; Burma secured their independence from Britain in 1948, and the French were driven from Indochina in 1954 after a bitterly fought war (the Indochina War) against the Vietnamese nationalists. The United Nations provided a forum for nationalism, post-independent self-definition, nation-building and the acquisition of territorial integrity for many newly independent nations.
