You trust everyone that has nukes to not mistake it for an attack on them and trigger mad?
Yes. They're not Americans, they don't "fear for their life" and start blasting. The US needs to be taken down carefully, like a hostage taker with their knife to the world's throat. If the US nukes Iran, I think that's the point where the EU and UK start treating the US as the single biggest threat rather than just one of many, but it makes no sense to attack the US openly and guarantee MAD.
What we need is a revolution in the US that is homegrown enough that nuclear command accepts their call to not launch nukes over the presidency's call to launch them. A military coup would probably be safest.
