Thatās just rhetoric, which is why I never worried about Iran, Iraq, Libya, or North Korea being nuclear powers. I would prefer, if I had my wishes, that there were NO nuclear powers. And donāt understand why the US needs to be the boss of who has them and who doesnāt. Particularly sense the US is the only country to have used them. Gaddafi, seeing what happened to Saddam Hussein voluntarily gave up his nuclear program and he was still killed and his country destroyed. I donāt blame Iran and North Korea for seeking to become a nuclear power as a survival means, not to actually use them. Any one of those countries would be turned to sand if they ever actually used them, and they well know that.
The JCPOA was working. Trump was briefed back in October however and informed that Iran had enriched uranium 12 times over what they had when Trump withdrew from the deal.
