It's not Vegas

A big part of the world's concern about Iran is that its nuclear facilities are numerous and well-fortified. There isn't one big potential bomb-producing reactor that can be knocked out in one blow as the Israelis did in 1981 in Iraq. But Edward N. Luttwak points out we can succeed:

An air attack is not a Las Vegas demolitions contract, where nothing must be left but well-flattened ground for the new casino to be built. Iran might need 100 buildings in good working order to make its bomb, but it is enough to demolish a few critical installations to delay its program for years -- and perhaps longer because it would become harder or impossible for Iran to buy the materials it bought when its efforts were still secret. Some of these installations may be thickly protected against air attack, but it seems that their architecture has not kept up with the performance of the latest penetration bombs.

Nor could destroyed items be easily replaced by domestic production. In spite of all the claims of technological self-sufficiency by its engineer-president, not even metal parts of any complexity can be successfully machined in Iran. More than 35% of Iran's gasoline must now be imported because the capacity of its foreign-built refineries cannot be expanded without components currently under U.S. embargo, and which the locals cannot copy. Aircraft regularly fall out of the sky because Iranians are unable to reverse-engineer spare parts.

The bombing of Iran's nuclear installations may still be a bad idea for other reasons, but not because it would require a huge air offensive. On the contrary, it could all be done in a single night. One may hope that Iran's rulers will therefore accept a diplomatic solution rather than gamble all on wildly exaggerated calculations.
