Pakistan and North Korea have nukes too.  I seem to remember a big song and dance with the North Koreans about fire and fury, and the promise of a great deal?  That episode is a key reason why literally no one in the world believes that Trump has the skill or brains to make a sustainable deal here either.  If you get bullied and tricked by a famine state like North Korea, no way in hell he can pressure the Russians into a deal worthy of the name.  

Man is just weak and stupid, zero national security deals which have worked.
