...you don't do that. Assuming you are right and Trump gets a second JCPOA in place, how are we not better off now with all the other gains I listed?
Besides, wouldn't the first JCPOA have expired by now?...in which case Iran would have been free to develop a nuke? Obama just kicked the can down the road to Trump anyway.
But, don't worry. If the Democrats beat Vance or Rubio or whomever, they can always undermine what Trump accomplished. Do you support the US paying war reparations to Iran?
