hugo Chavez. He was a guy that was a career politician that got too powerful. He used the poor as a platform to get what he wanted Not what teh poor wanted or needed. But that is neither here or there.
He was a typical strong man politically. Only he didn't have enough power to get a complete lock on the country.
As far as Venezuela Becoming a"Mortal Enemy" of the US of A. Nah Not really. There's too much of a connection business wise. Think Conoco. As far as Chavez goes, he just yelled and blamed the U.S. for whatever would keep his supporters happy and in his pocket.
He actually had some sort of stability compared to what things could've been like.
Now with his passing and no one to fill the void, There's nothing to really hold things in check. The Cartels from Mexico have been trying to get a more concrete hold of Central and South America for decades. This will be their golden opportunity. The Columbian rebels FARC, will have a whole frontier to play in. Chavez tolerated them in limited dosages and gave them a little breathing room, but that allowed them to galvanize connections. They will most likely take full advantage of being to fully operate in Venezuela without the limitations imposed by Chavez.
I don't see a good future for Venezuela until all the aftermath of his death plays out.
