You mean we should get democracy on the march in Iran and hope that free elections will install a Western-friendly government?
Given the recent failure of that Beltway dream in Iraq, I wouldn't hold your breath.
Hey, I never said it was a great option. I just think it's the best of a bad lot. I think bombing will only delay, not prevent, Iran's nuclear capabilities. And if the Muslims out there dislike us now, just wait until we hit a few schools by accident. This Slate Magazine article
has a good discussion on the Iranian nukes problem. On the feasability of the military option, it says:
"So, what if diplomacy does fail? One thing is clear: The Israeli air force has spent the last several years preparing for that possibility. They have reportedly practiced bombing runs against a scale model of Iran's Bushehr nuclear reactor, which they have built out in the desert. They have equipped all their F-15I and F-16I attack aircraft with external fuel tanks; each plane now has a combat radius of over 1,500 milesmore than enough to reach the real Bushehr and several other nuclear facilities. Israel has also acknowledged buying from the United States 500 BLU-109 air-to-surface bombspopularly known as bunker busterswhich can penetrate seven feet of reinforced concrete.
"However, some defense officials say this isn't enough. The Natanz facility, site of Iran's uranium-enrichment, is dug deeper still. The BLU-109 doesn't release a powerful enough blast to destroy Natanz. The site would be damaged, and the enrichment would probably be set back by several months, maybe even a year, but that's all. Meanwhile, the airstrike would likely spark a war with Israel (including stepped-up attacks by Iranian-funded Hezbollah), rally regional and international support for Iran, and stiffen the Iranian people's support for their besieged regime.
"If the United States joined in an airstrike, pounding the nuclear sites with repeated attacks from bombers and ship-launched cruise missiles, Natanz and the other facilities probably would be destroyed. Some U.S. officials fear that, for this reason (and because an Israeli attack would be widely interpreted as having an American stamp of approval in any case), the Israelis might launch an attack with the intent of drawing in the United States."
The rest of the article is well worth reading, though the author admits he doesn't have any good answers either.
