Thorniest Issues Left for Future "Final Deal" I’ve learned details on the latest proposal from the US to Iran to end the war which includes significant financial concessions to Iran. As expected, it would be a multi-step process, building on a previous 14-point proposal. The proposal is a Memorandum of Understanding (MOU) that sets up negotiations toward a “final deal.” It kicks the can down the road on the toughest issues so that the war can end.
