That it will not have horrible consequences for us, no matter where it happens.
I didn't say it was ok. That's just another strawman so you can duck defending your preposterous scenarios of Russia and China giving nukes to ::waves hands:: somebody who would then nuke us. Even you realize how dumb it sounds, so you're just trying to forget it and move on. Problem is, it's your justification for this failed war, which is more likely than not going to convince Iran having nukes is the only thing that will stop us from bombing them again.
You won't address it because you're just not capable of creating an even semi-plausible scenario where Israel and Iran exchanging nukes turns into WW3.
Your efforts were either ignorant (e.g. Netanyahu arrest warrant that already happened) or so ridiculous in their formation you can't even attempt to defend them.
