It’s possible we have de facto control of the regime through some backroom that only the Trump Administration knows about, but that’s just speculative on my part. We don’t know this is actually the case, and thus far there hasn’t been anything to substantiate the existence of such a thing.
So we’re at at a point where if put on the spot, gun to my head, I had to answer whether the United States controls the Government of Venezuela in any meaningful way, I would have to say “No” despite what Trump himself said. This is subject to change, pending further evidence made available to the American people.
