Do you have proof that Iran is supplying insurgents in Afghanistan? There seems to be some suggestion, but still no direct proof, that they are supplying insurgents in Iraq, but no proof that I have heard of that they are supporting the Taliban in Afghanistan.
I think we should really calm down with the rhetoric and pony up with some actual evidence. We can say all we want about nukes, but none of us know for sure. Hell, seriously, even that big comment about "wiping out Israel" was proven to be a mistranslation. Does anyone have any other quotes along those lines? I think it would, you know, be helpful, if someone supplied that.
Iran will not attack Israel either, because Israel has nukes, and everyone knows it. If Israel is on the verge of being wiped out, the Middle East will become a giant radioactive crater. Now imagine if you've got two states, and either one of them being attacked will mean the other one goes as well, what do you get? Enforced peace. Yes, exactly, if Iran and Israel both have nukes, the Middle East will become more stable.
Additionally, I'd like to say that comparing Iran to Nazi Germany is an insane overreaction. No one is on any policy of "appeasement," everyone wants to stop them having nukes except for the people who helped them get them. They're being allowed to proceed with a CIVILIAN nuclear program because the Nuclear Non-Proliferation Treaty permits them to, because it's legal.

Look at this, how does this look? Does it look like a third-world hellhole run by a genocidal maniac? No, it looks like a Western country where the girls have slightly different fashion.
