No don't worry, I'm not about to go all Cheney on you. Military action in Iran by us or by Israel is not possible. The targets are too deep, too numerous, and probably not all identified. We can't accomplish our goals that way, and we never could have even had we done something back when Cheney was calling the shots. All that we would do is ruin the ongoing opposition movement which, though certainly not a liberal one by western standards, certainly would be by Iranian standards.
The so-called "crippling sanctions" against the regime and particularly geared towards the Revolutionary Guard should be engaged immediately without further delay. No muslim state in the region would object since the Shiite Persian regime stands as a threat to all Sunni Arab regimes to the west. Afghanistan and Pakistan are largely irrelevant. Only China and Russia could object but doing so would simply expose them for the rogue nations that they may be trying to avoid becoming (well China anyway, the Russians don't generally care much as they have their own oil but just like sticking it to the west and the US in particular for not somehow preventing the Russian slide into a crime ridden alcoholic haze in the post-cold war era).
Strange bedfellows could be made from such an arrangement, especially if it succeeds enough to instigate some manner of Iranian lashing out before they actually manage to enrich enough useful weapons grade uranium. Israel, Saudi Arabia, and Syria anyone?
What do we have to lose by trying???
