Indeed. The US is never going to pay compensation to Iran. Not only that, I am sure it won't unfreeze even our own blocked assets and money in foreign countries. That's why they are never going to accept a verification mechanism. That's just impossible to happen. Even psychologically, the US is too proud to accept such a condition and that will render the US weak in the eyes of the international community.
I agree that Iran's conditions are intended not to be met. They are too strict and unrealistic. They are so unrealistic that they are probably for propaganda only.
However, I won't be surprised if a deal is reached between Iran and P5+1 in silence.
It will be a much weaker version of the JCPOA. Basically, Iran will keep its uranium stockpile but it promises it won't escalate further and the US will ignore some of the sanctions, particularly related to the energy sector, while theoretically keeping them in place for future use.
In case of Iran, that probably means a limit on some of the aspects of our nuclear program like restrictions on employing IR-8, IR-9 and IR-10 machines and giving up the reconstruction of the IR-40 nuclear reactor (which was supposed to start early this year and finish in a short time but we do not hear anything about it). On the part of the US, that would mean that they would allow their allies to import oil from Iran and return our assets to us in silence without media coverage.
We probably already have this covert agreement at this very moment and that's why Italy is importing oil from Iran (even though they claimed it was a mistake and they did not the origin of the cargo) and the Raeesi government recently said that $3.5B of our frozen assets have been paid to us by several countries but they cannot talk about it publicly.
I had earlier posted this very suggestion that Iran and the US should reach an agreement where both sides will covertly agree to a very weak version of the JCPOA and refrain from escalation.
@Shawnee said it was a weak deal, but I believe it's excellent for both sides and it is practical. Both sides will keep what they have (nuclear stockpile in case of Iran, sanction regime in case of the US), but they will defuse tensions during the Biden administration. If my suggestion is close to the truth, we will not see any major development in Iran's space program any time soon.
