Norman Podhoretz on the case for bombing Iran:
At the outset I stipulated that the weapons with which we are fighting World War IV are not all military—that they also include economic, diplomatic, and other nonmilitary instruments of power. In exerting pressure for reform on countries like Egypt and Saudi Arabia, these nonmilitary instruments are the right ones to use. But it should be clear by now to any observer not in denial that Iran is not such a country. As we know from Iran’s defiance of the Security Council and the IAEA even while the United States has been warning Ahmadinejad that “all options” remain on the table, ultimatums and threats of force can no more stop him than negotiations and sanctions have managed to do. Like them, all they accomplish is to buy him more time.
In short, the plain and brutal truth is that if Iran is to be prevented from developing a nuclear arsenal, there is no alternative to the actual use of military force—any more than there was an alternative to force if Hitler was to be stopped in 1938.
Read the whole thing. You may not agree with this viewpoint, but it is the most compelling and coherent case I have seen to date for this course of action.
