"United States control of the Philippines was never intended to be permanent. From the beginning, the colonial mission was seen as one of paternalistic "tutelage"—of preparing the nation for eventual independence—and aside from a few "retentionists", the question was generally not if, but when, independence would occur."
The U.S. fought a brutal war against Filipino independence from 1899-1902, but progress continued towards self-rule via the Jones Act of 1916, the The Tydings–McDuffie Act of 1935, and finally the 1946 Treat of Manila which relinquished all U.S. claims to sovereignty in the Philippines.
