Well that's alot of heresay not sure it debunks.
I think the original photos of Colombians making molotovs were Colombians trying to stop Venezuelan refugees from entering Colombia, not sure.
While I dont doubt the CIA wants a good coverstory and Pompeo sounds like a Roman, trucks passing either way on that border would be stopped for a long inspection and vulnerable to any attack. Any refugees passing through available to hire for any cause either way.
If its anything like Nicaragua there is a sense of urgency on the ground from Venezuelans who want Maduro out, just like plenty of Nicaraguans want Ortega out.
They have failed into the face of globalism.
