You do not want to be a white boy walking around in Venezuela right now. Especially military aged, clean cut, etc. Good way to get snatched up...
As for the russian deal, yeah when it jumps off, I imagine Russia is going to attempt to sell the weapons and ammo, probably try to get a foot in the door on their oil production, in an attempt to steer prices, etc.
Venezuela's been on our "freedom" list for 20+ years, we will be in there, if we are not already. Brazil and Colombia are all in on cleaning that place up as well. We ain't talking Syria here, a couple of bombers and maybe a sub is about all the influence russia can project in our hemisphere. And that won't last very long, unless Trump really is on Putin's payroll, I don't see how this ends well for Russia in any way. In other words Putin is biting off way more than he can chew.
