New nulear site in Iran

How come if we know there is a site at Qom, Iran that we don't bomb the crap out of it? If we don't have the cajones, then why don't we hire the Israelis to do it? They have one made of brass and the other made of steel--and you know the rest. One small tacticl nuke bomb should do the trick. Diplomacy is not the answer--POWER is the answer and always has been in this case.
