As concerns global stability a single precision strike from an untouchable platform with zero marginal increase in obligations on strained naval assets is basically the best case scenario. If we had dropped a bomb, took a picture in front of a "Mission Accomplished" banner, and gone back to playing chess with peer adversaries in any conflict since the Korean War it would have been the smart move. The United States military is designed to protect global trade and win high intensity conflicts against peer adversaries and be seen preparing for it as a deterrant. It does this job extremely well. It was not designed for assymetrical quagmires with no possible palatable exit strategy.

Likud may be willing to fight Iran to the last American, but I'd rather we didn't.
