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.)
United States territorial acquisitions
Preparation for a fully sovereign state was interrupted by the Japanese occupation of the Philippines during World War II. The United States suffered a total of 62,514 casualties, including 13,973 deaths in its attempt to liberate the Philippines from Imperial Japanese rule during the hard-fought Philippines campaign from 1944–1945. Full independence came with the recognition of Philippine sovereignty by the U.S. in 1946.
