Herbert Adams Gibbons
In the early 1930s, Gibbons argued that an American withdrawal from the Philippines would be futile, because Japan would immediately colonize the country if the United States were to pull out. In 1931, in a speech in Manila, Gibbons referred to the Philippine calls for independence as "claptrap." He said that if the United States were to withdraw, then it might as well negotiate with the League of Nations to hand the Philippines over to Japan as a mandate. The American business community roundly praised Gibbons' speech. However, Philippine nationalist leaders attacked Gibbons, saying that he was raising the "Japanese bogy" as a hurdle to Philippine independence. (Ultimately, the United States did not grant Philippine independence until 1946, after Japan was no longer a military threat to the former colony.)
Treaty of Manila (1946)
On July 4, 1946, representatives of the United States of America and of the Republic of the Philippines signed a Treaty of General Relations between the two governments. The treaty provided for the recognition of the independence of the Republic of the Philippines as of July 4, 1946, and the relinquishment of American sovereignty over the Philippine Islands.
