trance,
I'm familiar with OpSec, I worked at one of those three letter agencies with the appropriate clearance but thanks for your concern.
Before posting I checked with a good friend of mine, a retired SEAL Commander, that currently works with Southern Command (Venezuela AO). He said it's probably something to do with FMS of Apaches to S. America but I could not find any info on it.
I grew up in S. Florida and "Little Venezuela" (Doral) is near my house. I met many Venezuelans that hated Chavez and wanted him dead. The same thing happened with Cuba, everyone with money left.
I found it interesting as Maduro was in China for meetings with them, most likely a bailout. I doubt if the US wants China to get a foothold using their "Debt Diplomacy" tactic as they've done with other countries.
The attempt on Maduro's life was with a helicopter by a former Venezuela FBI agent (trained at Quantico?).
And then there are these meetings: link
Supposedly Maduro is considering having the US FBI help him find out who is after him. Really????
Anyhow, I find these things interesting as from 1975 to 1992 I was involved in staffing international projects for defense support and training contracts. You can be sure the CIA and US military have already gamed a number of scenarios to make an intervention.
