All this "war" and "constitutional" business and what have you is all completely besides the point. Unless we're talking about a full fledged invasion of a sovereign state, then the President gets to do whatever he wants when it comes to military operations. If the commander in chief wants to deploy a small amount of troops or planes or ships to defend American interests, he can do that, especially when we already have military forces operating in the immediate region. That's the way it's always been and that's the way it always will be.
Lief literally becomes a fire-breathing imperialist when a Democrat is doing the bombing. I for one think that Obama, Bush, and Clinton should all face the chopping block for their crimes, no matter whether they ran under the elephant or the ass.
