you dont send the choppers in until the air defence is neutered. What do you think a few dozen specaial forces are doing in Caracas?
I don't presume to say, other than there can be a lot of possible missions other than decapitation. Their army has ~120K and they've been expecting stuff to go down for months. This "deal with a general" you're suggesting is very hand-wavey.
I’ve seen videos of what are clearly MH-47s over Caracas.
Presumably there are SF and/or airborne units executing coordinated strikes on the ground right now. Most likely the 160th, as they were deployed there last I checked.
