> The Philippines was a large American holding in the South Pacific "holding"... looks to me like the whole history of the Philippines as a US colony has been written out of history.
I can't speak for your schools, but it was in my history classes as well as commonly mentioned in almost every book about World War II in the Pacific I've read.
I think it’s safe to say that most Americans have little to no understanding of this history. Maybe “written out” is an exaggeration, but “quickly glossed over and afterward ignored” would be a fair summary.
