I agree with GotSand (holy F!) Let them sort it out. It is thier war not ours...BUT...if it breaks to a larger thing with Syria and Iran, we will have to step in. Israel is an ally of the U.S. We expect out allies to help us, we will have to help them.
Saw a funny factoid yesterday...
Lebaniese spends 500 million a year on their army
Israel spends 10.4 BILLION a year.
