No; it was to keep Europe away from the rest of the Americas so that they would not threaten the USA’s southern borders. Is this a way of saying that Kerry declaring it “over” was a good thing for the USA?
As for “endless wars”, Washington warned the USA to be “at all times ready for war” rather than thinking we could eternally be isolated from that scourge, or “avoid insult” without “be(ing) able to repel it”; he was the first to promulgate “peace through strength”, as Reagan later articulated the policy. Things had gotten so decadent under Wilson that he could actually get successfully re-elected on such a craven slogan as “He Kept Us Out Of War”. The people were not afraid of Germany for no reason, in spite of that.
Again, you are wrong. One of the great challenges Wilson faced in his efforts to get America into the war was the Monroe doctrine.
It was seen throughout our government as a separation between the old world and new world. Unless someone attacked America, we also were secure that idiotic European wars did not involve us. The part of the Monroe doctrine you are referring to was intended to keep European wars from spilling over to the Americas.
It worked well until Wilson wanted to jump into a European war.
