It makes perfect sense that the US should turn some of its heavy bombs and remaining nuclear missiles around and aim them at Iran. After all, the price of being a nuclear power is that you also become a nuclear target;  both the US and the USSR always knew that, which is why they never used nukes in the whole 40 year Cold War.  Certain Islamofascists, however, neither realize that nor understand what a nuke can do.  They simply think that having nukes makes them the biggest bullies on the block, and sooner or later they'll start pushing their luck.  Israel knows this, and expects that Iran will push its luck on them, so they've taken steps of their own to defend themselves. 

If the US waits until Israel is obliged to attack Iran, every Arab country in the middle-east may try attacking Israel -- and that would lead to a serious all-out war, not just the slow attrition that the US has been playing with in Iraq and Afghanistan.  Nobody, except possibly the Islamofascists themselves, wants this to happen.

 It's very likely that the only way to prevent this scenario from playing out is for the US to attack Iran first, preferably with something less than nukes.  Of course we'll need a good excuse for it, but there's no reason to assume that the US needs to manufacture one.  Ahmedinejihad seems quite capable of providing such an opportunity by himself. 

The ideal situation would be for the US to have missile-hunting drones in place that can detect and shoot down any missile (or bomber) that Ahmedinejihad throws at Israel, then claim -- or reveal -- that the Iranian bomb was a nuke aimed at Tel Aviv.  That would be excuse enough for a bombing-run that would pound Iran flat, leaving it in no condition to attack anybody.  Even that famous fiction, World Opinion, would have a hard time arguing with it.

In any case, may I ask why anybody is preparing to weep and wail over a dangerous religious fascist and his flunkies?  There are some people too dangerous to be allowed to live, you know.  And there are some things worse than war.
