I can't think of a realistic, non-cynical reason that doesn't begin and end with "oil" for even looking funny at Venezuela. The whole "drugs 'r bad" thing doesn't wash.
There are a couple of things I can think of. There's the human rights stuff with torture chambers and a third of the population leaving which doesn't seem to bother Trump but the Venezuelans don't much like.
Gotta be honest: "the human rights stuff with torture chambers" sounds like a bonus to a Trumpista. MAGA is not known for its progressive stance on human rights. More the opposite, really, as long as it's not them doing the suffering (or even being mildly inconvenienced).
