The OP is not onto anything. That Russo interview is all hearsay and that's it. I don't give a shit about how Hugo Chavez died. He died from an infection following cancer treatments and surgery. He was in poor health. No grand conspiracy afoot. Russo's interview gives no evidence to support a conspiracy.

If our govt or military wanted him dead, troops, aircraft, and/or drones would be used. The US didn't care about Chavez because he was a whiny blowhard and Venezuela is a shithole.
