I see this as friends helping friends destroy a common enemy and I think this is great news. Believe me, the United States will not be taking over the holy land. This I am 100% sure of.
In my humble opinion, the best thing for Israel is not to attack Iran on her own. We cannot deny America's military might. In a situation like this, the U.S. is a good friend to have. The attack on Syria's site was a different case, and was easily handled by Israel alone. Iran is different. And their nuclear sites are not as easy either.
