Iran needs 160kg @ 20% over 5 years for the TRR, and it already has about 120kg. Iran will offer this: once it gets to 160kg it will cease 20% enrichment. A "win-win compromise" would be this: Iran mothballs (but doesn't dismantle) Fordow, keeps 32kg to make into fuel rods, sells the remainder, and has an iron-clad quarantee that it can buy pre-made fuel rods from overseas. That does two things: (1) gives Iran a one-year buffer in case the USA reneges on the fuel rods, and (2) it gives the USA plenty of time to react if Iran starts up Fordow again.
