Destabilization = bad
Iran with bomb = destabilization
Also the whole proliferation thing.
It's not about the actual use, no country would ever dare use them nowadays. It's more about the whole power thing, Iran getting the bomb means they just knocked themselves up a notch in the region, and are more likely to bully the smaller states around into doing what they want. That's pretty destabilizing to the region.
Ah, I see: If Iran projects power in the region instead of the US and US puppets projecting power in the region that is called "destabilization".
These guys make American Fundamentalist Christians look like a Gay-Pride parade. To allow them to have nukes is inconcievable. They don't think or negotiate like Western leaders. God's holy vengence for past injustice - real or imagined - is high on their to-do list.
"Past injustice - real or imagined"?

You
really want to put it like that?
How many times did the US, the UK, US and UK puppets invade Iran over the course of the 20th century, again?
This is not a rhetorical question. Cause i've lost count...
As for evidence, there would seem enough of it to create an unlikely coalition of states (China, France, Germany, Russia, UK, USA) working together to try and stop Iran.
The evidence includes but is not limited to;
Irans' violation of UN Resolution 1696 to suspend all enrichment and processing activities.
The frequent removal of IAEA seals and cameras at Iranian nuclear facilities.
The general secrecy and hiding of facilities underground, and lack of cooperation with international inspectors.
The development of the Shahab and other intermediate range ballistic missiles - a standard nuclear weapon delivery system.
The November IAEA's report that Iran is about to make a nuclear warhead small enough to fit on a ballistic missile.
Iran's recent announcement that it had achieved 20% enrichment - the threshold for atom bomb construction.
There's quite a bit more, but this is, afterall, just a game site.
Two points:
a) What you are proposing is nothing short of a "war of aggression" - a war crime. Unless you'd get a UN resolution to authorise such an intervention... which you will never get. The US allready commited that war crime this century and this would be ten times worse in terms of diplomatic repercussions.
b) Everything you said is just as true for Israel, only that they don't have to put up with controls and such nonsense cause they refused to sign the treaty to begin with. And i fail to see how the Israeli leaders are any different in terms of religious zeal or aggressive rhetorics.
Oh, plus there is a pretty good chance that Israel violated UN Resolution 418 in the worst possible way, which would be roughly the worst transgression in terms of nuclear proliferation any nation has ever commited since the early 50s.
So i guess you want to bomb Israel into submission, too?
They are cranky old men. Intolerant and hateful. Incompassionate and vengeful. Religious hard liners who see Satan everywhere they look. They're not rational like Western leaders. They're unpredictable. Dangerous. The world would be a lot safer if these guys didn't have nuclear weapons.
Bush and Cheney are building the Iranian bomb?
Re: Would the Nazis have used the bomb?
a) Yes, probably but only against Russia.
b) You guys are seriously obsessed...
