There is no reason whatsoever to enrich uranium beyond like 20% if its not for military purposes in such quantities.
Saying that others are NPCs is interesting. How do you know that you are not an NPC?
If Iran gets nuclear weapons, all big Sunni countries will get them too: Saudis, Qatar, etc. we do not want it to happen, as the next Arab spring can collapse those governments, and you can count on any Muslim radical group getting hands on one of those.
Anyway, there are countries that have nuclear weapons, and this Jinny is out of the bottle. But, it doesn’t mean we want to have more of this crap lying around. We need less.
At this point, every country which has natural resources which the US might want to steal should have nukes.
Except they don’t.
North Korea minds their own business.
When Iran builds a base in Mexico or Canada, we can talk.
