Try again when we live in a timeline where the American response to the Philippines wanting to be independent in 1898-1901 is not "bloody suppression".
Granting them their independence in 1946 doesn't undo that happening in the first place, much as one might wish.
Yeah, I gotta agree with Elfwine on this one. Though I think they did realize they fucked up and set the Philippines on a path to independence afterward. And Puerto Rico was undeniably ruled as a colony until the 1940s.
