This presumes we know what and where to bomb, given the state of knowledge on Iraq's WMD programs (while we spent a decade overflying the country and one would hope creating human intelligence sources inside) I don't see public (or more importantly/immediately Congressional) support for a bombing campaign that can't resolve anything. The administration is not going to open that can of worms while still trying to stabilize and minimize the issue in Iraq.
Israel must be defended.
That's why Israel has a military and nukes of their own. Unless and until we add Israel as a U.S. state or territory it is not ours to defend.
They can deliver bombs to Russia, Western Europe and places in between. A whole lot of the world needs defending against the mad mullahs.
