Trump and the Iranians say we are close to a deal, but they disagree on what the deal is. Trump’s version is that the Iranians have agreed to give up their nuclear material, but that the means by which it will be done are subject to subsequent negotiation. The Iranians say the whole nuclear issue is still on the table and will be discussed later.
In either case, the ultimate resolution of the nuclear issue is left until later. If the negotiations are successful, the outcome will be an updated Obama deal. Trump will have caused lots of death and destruction in the Middle East and plagued the rest of the world with shortages and higher prices essentially to recreate the deal he tore up in his first term. If they fail, Trump will have to escalate or, as is more likely, walk away without accomplishing any of the goals of the war.
Sounds awesome, doesn’t it?
