You have no solution then
I offer the solution that denuclearized Ukraine and halted ROK. Japan, and Saudi ( we hope)
And the only pragmatic suggestion to halt nucs in Iran and if that works, perhaps NK
but they will be under Russia or China, not us
Iran Leadership isn’t even close to Ukraine, Japan, nor Saudi in how they were approached on nuclear... so that’s a weak arguement to expect Iran would even consider. It’s a terrorist state that operates in proxie conflicts and will always play on any side, and quick to change, that they stand to gain ground and this with their eye on the goal of establishing other Islamist states....and no Islamist state will ever “be under the USA”.....and you make it sound like Irans association with russia and China is somthing new....it’s not.
There will never be peace for long in the middle east....at most cease fires and exactly as we’ve seen played out....they scurry back in their holes until the next time they raise they’re head to fight.
