a pretty epic diplomatic achievement. They're giving up an awful lot, and what the West is doing is not punishing them economically so much. When you look at the details, it probably helps to consider that if there were no deal--we would actually not get any of this. They'd still have the same amount of uranium, keep all their centrifuges, and enrich it to whatever the hell degree they like. The alternatives to negotiation that some people seem to favor, which is war, is conceding billions of dollars and lives, compared to which, giving up some sanctions that can always get slapped back on with a resolution pretty much sounds asinine.
What I'm saying is: I genuinely think most of the critics haven't looked over the details, and are making no sense. Their complaints are a little like a dog barking at a vacuum cleaner. Something's going on, they don't approve, woof! Dumb, kneejerk "appeasement" rhetoric just doesn't line up what has actually taken place. (It's especially rich when Jeb Bush tries to use it, but frankly, he doesn't seem to understand foreign policy--period. Too many big-syllable words, I guess.)
This achieves what 30 years of hostility hasn't done. It's a big freaking deal. If we had an informed, sane national dialogue, the reaction would not be so partisan.
