If you say that Israel does not benefit from this War, do you care to explain why they are not better off with Saddam out of power?
Because he was a secularist who was the main obstacle to the spread of militant Islam. It is true that he was hostile and very annoying toward Israel, but those who will replace him will not be any friendlier. The Reagan policy to support Saddam Hussein was beneficial for Israel even if Israeli (and some American) Jews refused to see it.
Same was with the last little war of Israel against Hezbollah in southern Lebanon. It was very harmful for Israel although it satisfied emotions of anger and frustration among Israeli Jews.
Those on the right (or left) who wish ill to Israel should call for an attack on Iran. Read my tagline.
