This intervention of Eisenhower's may have done more to put an end to European colonialism than any single event in the postwar period.
Maybe that was a good thing, because it got a difficult process over with.
In any case, the whole business has been thrown down the memory hole, because leftists simply cannot admit that the U.S. did more than the U.S.S.R. to end colonialism.
The U.S. never had colonies in the European sense, and it never supported colonialism. We did intervene in places like the Phillipines and Cuba, but not with the intention of building a colonial system like those of Britain and France. But the left simply refuses to admit it, because the U.S. has to be the chief villain.
Well, Puerto Rico was/is a colony in the European sense, one that should have been cut free (like the Phillpines) immediatly after WWII.
