I believe it was Tredrick (sorry if I'm wrong) that proposed that we send aircraft over Caracas to deliver food to the slums. First, to show that we oppose Chavez, not his destitute populace and second, to show that we can overfly his country unstopped at any time. Good plan for right now.
That was my idea
As far as threats go, yeah, this is pretty meaningless. However, Chavez was doing better when it was just him versus the U.S. It played well in most of Latin America. Now it seems that he want to make everyone choose sides. Sorry, Hugo, but most of this hemisphere may dislike the U.S. and quietly applaud your criticisms, but when push comes to shove (as in the FTAA issue), most countries would rather be on our side.
