The one thing is that the Americans had absolutely NO business to be in the Philippines at this time.
The Philippines used to be a Spanish colony ( 1521 - 1898, actualy the Spanish never managed to subdue the Muslims in the south).
Starting from the mid 19th century there was a rebellion developing in the Philippines against the Spanish colonialists (Rizal, Bonifacio, Aquinaldo, the Katipunan-movement, short KKK, etc., but there have been local rebellions going on in all region, the Roman-Catholic ones as well during the whole time of Spanish rule).
The poet and doctor Rizal, the intellectual leader of the rebelion was executed by the Spanish in 1896.
In April 1898 the American battleship Maine exploded in the Cuban port of Havanna (at this time a Spanish colony), leading to the Spanish American war. Spain lost the war and as a result lost it´s colonies in America and Asia.
Most Filipinos, based on the American history (indepence war) saw the Americans as a help against Spanish colonial rule, esp. after the Americans destroyed the Spanish fleet in Manila bay and hoped finaly to get national independence. General Aquinaldo declared the independence of the Philippines after helping the Americans in the war against the Spanish.
Most Filipinos were deeply disappointed, when instead of letting the Philippines become independent, the US declared the Philippines to be their colony after the treaty of Paris. The in meantime accepted constitution and the new President Aquinaldo were not recognised by the US government. After some Filipinos have been shot by the American Army, Aquinaldo´s revolutionary congress declared war against the US.
This lead to an armed rebellion (American -Filipino war) which lasted until 1911. It was the first Guerilla war in Asia, with 4200 American casualities, 16000 Filipino guerillas and 200000 Filipino civilians. BTW, this rebellion again included both Muslims and Christians.
Even though the Americans developed the country quite a bit, resentments kept going on.
Only FDR wanted to end the colonial rule in 1943 and started from the 1930s on to replace American colonial officers with local people.
Unfortunately the Japanese invaded in 1941 and Filipino guerillas found themselves suddenly fighting side by side with American troops against the Japanese, which eased the relations. In 1946 the Philippines became finaly independent after a referendum.
The US government still kept on interfering in this country, not the last due to pressure by big fruit companies (Dole, Del Monte), which own huge pineapple and sugar cane plantations, esp. in the Muslim south.
President Magsaysay, who started reforms, also against the local plantation owner´s aristocracy got killed under misterious circumstances in a plane crash.
The dictator Ferdinand Marcos could have never stayed in power for such a long time (20 years) without outside support.
Sorry about my rant, but due to family connections (my daughter is half-Filipinab)I´ve got a personal interest in the Philippines
