We would need to give Iran a very attractive offer for that. They are aware of our internal politics, and want the Republicans to do poorly. They are also very distrustful of us, so any benifit to them would neec to be front loaded. But once they get the front loaded benefit, they have no reason to follow through.

Assuming you get through all of that, Iran can not just flip a switch and fix the global energy market if they wanted to. Infrastructure has been destroyed, supply chains have collapsed, and tankers are slow.
