Reality check.
Nobody is talking about Chavez invading the U.S. All the talk about invasion is the other way. What Chavez is going to do is make trouble throughout South and Central America, supporting radicals with cash and stirring things up.
Not dangerous, IMO, but it's going to make life harder than it needs to be, and could create economic problems in the future. We need more radical nutballs in the world like a Channel swimmer needs an anvil.
