22 years ago I seem to recall American service personnel helping gleeful Iraqis tear down a statue of Saddam Hussein.
Attitudes amongst the Iraqi populace towards the Americans modified quite quickly thereafter.
Maduro clearly lost the last election, and a majority of Venezuelans want rid of the regime. The thing is, they aren't rid of the regime, they're only rid of Maduro. Even if Mr Trump does succeed in imposing Marco Rubio as some sort of Governor-General (which seems to be the current plan), a substanial minority of Venezuelans remain Chavistas. Are they going to go quietly into the night, or are they going to resist the takeover? This has the potential to get very messy, very quickly.
