It’s understandable that Khamenei/Ghalibaf are so angry and trying to fix things as much as they can, but they should take into account that this deal will eventually be available to the public in the future in two different ways. Not only that these secret documents will be published in some decades according to the US law for example but it is closely linked to some scientific advancements. So it will be part of history nothing can be done to undo that. Whatever they do will make things far worse.
Khamenei is the symbol of deficiencies of centralized wisdom and Ghalibaf is the symbol of corrupt/power-loving politicians. Both ideas will have to be discarded.
Khamenei/Ghalibaf should let Parallelism handle the transition phase smoothly rather than make things much worse. They can’t stop it so they shouldn’t try to disrupt it.
They won’t be part of the process.
UPDATE 1:
What the US did was to protect its democracy. Trump had encouraged his supporters to invade the congress, they had to do something about it and they did it in a controlled way. Khamenei/Ghalibaf helped them to do that by harming themselves in unimaginable ways. Nothing can be done to make things better for the Khamenei/Ghalibaf camp. Not only the West will not hide such a huge historical win, but they will also teach it in universities for decades to come.
All they can do is let parallelism do things in smooth ways. Even if they want, they can’t stop the plan.
UPDATE 2:
Khamenei thought world leaders thought of him as a wise person whose wisdom could not be defeated. But it is now clear what the world really thinks of him. In fact, after Ahmadinejad things were very clear to the world.
I wasn’t involved but most probably, the negotiators approached Khamenei saying that the West realized his wisdom is undefeatable and the world acknowledges his depth of vision or something. On the other hand, knowing that Ghalibaf is a power-loving individual they approached Ghalibaf by offering him two power branches in Iran. He has been the Parliament spokesperson and he was offered to be the president in shadow. So he would be in charge of two power branches. He thought that would be the best deal possible.
Similar to the way the Khamenei camp made a mistake about the world’s perception of their wisdom, they made the same mistake about some of the people inside the regime who took a bow and admired Khomenei under any circumstances.
The regime is unstable and it had to let the parallelism to handle the transition phase smoothly.
