Once in office feel free to do whatever you want because 90% of USA is not aware of world outside its doorstep anyhow. Hence the last 50 years of US foreign policy. The Marshall Plan was about the last good idea we had in that arena...
... lessee ... uh, the Peace Corps? And the Grenadians sure were happy for the Americans to invade / intervene / rescue them (even if you would be hard pressed to find a majority to agree on which one of the three it was).
Well, OK, the Marshall Plan was the last big ticket item. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
