I love Ron paul's position of "Let ISR do what they want".
IMO, part of the problem - the ongoing mideast violence for decades - is that the US has prevented one side from winning. Granted, the world knows it'll be israel that wins, but why stop them? Do we go into the jungle and tell the lion to stop killing antelopes? Of course not.
In 2 years, israel would have the bad guys killed/moved outta there, they'd have the remaining civilians in check, and everyone on both sides would live safer. Why not let them handle their own business? If Mexico was sending suicide bombers into the US, and some country in europe tried to prevent us from bombing Tijuana back to the stone ages, we'd laugh in their faces.
