so what your sayin is that it would be almost impossible for the phil to be a state of the USA?
It would be very difficult. The US has never yet accepted a state where the majority of voters weren't white English-speaking Americans, IIRC. Hawaii was probably the closest case, but the American planters had firm control of the islands at the time...
If the US somehow kept the Philippines past WWII in a friendly relationship (maybe Japan never goes to war, or doesn't attack Pearl and is slowed/stopped by Free French and Brits, leaving the Philippines wanting/needing US protection), you might get Statehood after the Civil RIghts era.
OK. What if the US built up more in the Philippines in the late 30's, and treated the Philippine army as more than stupid grunts. (The later might be hard enough to do.) Then when Japan invades the Philippines (but doesn't attack Pearl), they don't win, or at least not nearly as fast. Oh, and succeeds in declaring war ahead of time. Thus the US might be prepared to simply defeat instead of destroying Japan. This could leave a strong Japan as threat, that requires a Philippines, ...
Still tough, but possibly doable. You'd probably have an independant, closely allied country that joined the US in the '60s? Maybe?
Changing the Supreme court decisions (which LOOKs like a possible PoD), would allow thousands of Philippinos to move to the States might actually hurt the possibility of the Philippines becoming a State, as there'd be a backlash.
