Nukes for Chavez?

As if it's not bad enough that North Korea and Iran are on the fast-track to developing nuclear weapons, but it seems Venezuela now wants to join in. I believe they only want to produce nuclear power about as much as I believe that to be true of the Iranians. Hugo Chavez wants to rule South America with a nuclear fist -- and it looks like Russia is willing to help. Are we going to be brave enough to do another blockade like we did with Cuba? Of course not. Nobody thinks Chavez is that big of a threat. But there's no bigger threat than a big fool, let alone a power-hungry fool who already has too much power. Are we ready to fight a world war on this scale?
