Honestly, the only reason I'm not actively rooting for Iran to acquire nuclear weapons is that I don't like the idea of a nuclear arms race in that volatile shithole of a region.

Viewed in insolation however, Iran having nukes would almost certainly be a good thing, as it would in all likelihood deter the US from starting a war with Iran (which would be disastrous for the entire world, not just Iran and America), and they would obviously not ever give nukes to the kind of terrorists who'd strike the US or Europe (those are pretty much all Sunni). I don't even think they'd give nukes to Hezbollah, and I don't even see them ever nuking Israel (due to the Islamic holy sites found in that country, and Israel's retaliatory capabilities). Iran's nuclear weapons would be for deterrence and self-defense purposes, nothing more.

Again, Iran is not run by suicidal death cultists, if anything the Ayatollahs have been quite cautious, and shown a great deal of restraint in response to vicious Israeli aggression these past couple of years. I'd trust them with nukes over the kikes any day.
