Venezuela's Chavez claims that CIA assassins are trying to kill him. Even if that were true, which it isn't, he sounds like a lunatic talking about it. Chavez obviously has no one around him who will tell him about this. Isolation for a guy at the top is never a good thing.
Chavez had a real opportunity to lead prior to the United Nation's sulfur comments about Bush. Now he adding to his image damage by going on about CIA assassinations. Who's going to ally with a guy like that? His unexpected outbursts make him scary to his friends, not the United States.
