So, once again, the stated goal for Iran is to keep them from having nukes (the war). The proposed solution (the battle) is to negotiate to convince them to decide on their own to walk away from the program. Known fact is that negotiations with Iran will be hamstrung from day one by the determination (by our side) that they do no negotiate in earnest. So we're choosing a battle that we know is crippled before we ever get started. Negotiation is the enlightened approach.
OK, in the case of Iran, I'm conceding that a crippled battle plan might be the best option we've got. But to turn around and say that our goal all along was to let them have nukes but persuade them not to use them is dishonest. That's not the original stated goal; that's not our stated victory condition.
And, once again, let's take this back to the general case. I don't think it's out of line to say that negotiation is being held up as the end-all and be-all solution to every problem. So, in the case where one side does not negotiate in earnest, you're going to the job site with a broken wrench when there's another perfectly good wrench on the table. That doesn't strike me as enlightened in any way--that's just plain stupid.
Here's where you're wrong. We don't know if they negotiate in earnest because we have not negotiated with them in thirty years. We're sure they're lying about building a nuke, yes - but they haven't pulled a Saddam or Kim Jong Il and made some deal with us only to break it later. Our negotiations with Saddam and Kim Jong Il were/are hampered by the lack of international support for our position.
This, however, is not the case with Iran. Pretty much no one wants Iran to get a nuke. Russia and China are taking advantage of the situaiton to make our lives more difficult, but "Tehran with a Bomb" is not in their interests either. I'm flat out saying our goal is to
prevent Iran from getting nukes. This may be an impossibility. They
may not respond to negotiations or sanctions, at which point I'm in favor of using a military option as I view the resulting blowback from that as less of a threat then a nuclear-armed Iran (as does virtually every expert in the U.S., I may add). The Ambassador even said that we should keep the military option on the table, because if we take it off then it will be viewed as a sign of weakness by Tehran and they'll just do whatever they want.
However, negotiations (or super duper sanctions) may indeed work. Our main issue is getting Russia/China on board. Obama may be able to do this, he may not. The point is, we won't know if we don't try. There would be a time table to this too, like the Ambassador said, probably. We wouldn't just sit around for six years and let the Iranians waste time while they build a nuke. His point is that negotiations cost us nothing, may give us a net benefit (even if they fail - we'll be more likely to get international support for sanctions or a military strike), and might possibly succeed in their goal (Iran stopping nuke program).
On the other hand, your immediate military strike gives us a
possible benefit of delaying the bomb by an uncertain amount of time (but most likely not a significant one - they have spread out their facilities quite well, it will not be like the Israelis blowing up Iraq's heavy water plant), gives us massive losses in terms of blowback from Iran, loss of international support, and futher destruction of US reputation overseas. Oh, and China and Russia will make a lot of money off the ensuing increased arms sales to Iran.
