Syria has always been the Israelis backyard. Let them handle it. The took care of that nuclear plant in 2007(Operation Orchard)
I know, I was in Al-Anbar province when that happened. If the Israelis would have attacked Syria at the same time we were conducting the 'invasion phase' of Iraq......it would have been outed as a concertated US/Iraeli plot. It would have touched off WWIII and been touted as a Zionist plot to commit genocide of muslims.
Iraq was always Israel's backyard too.....just like when they bombed the Iraqi reactors in the 80s.
