I don't know who Chavez's boss was, but I know his ethnicity, that's for sure.
Plus, I agree. Even the weakest country in the world would have some military able to shoot some bullets when a foreign power invades their country and kidnaps their president. It seems obvious to me that Maduro negociated his imprisonment. He even took his beloved wife with him. Maybe he will even "die" a mysterious death some years ahead and spend the rest of his days on some tropical paradise spending the money that he will get on this deal.
