Actually Deepfork, much of what has been claimed about that release of funds to Iran is simply not true.
The vast majority of that money was NOT held in the US, but rather in foreign bank accounts (in an escrow account), in the countries that had been buying Iranian oil for decades. As they were prohibited from paying for it, they still took delivery, upon agreement that the funds would be released to Iran if and when sanctions were lifted. Nearly all of that money was actually in banks within the borders and control of China, India, Japan, South Korea, and Turkey. The US held only about 11% of the total that was released.
Bottom line, it's exceedingly difficult to wield a carrot or a stick to try and influence what amounts to domestic production decisions in relation to any country which is a member of the WTO. (This is not just applicable to oil/gas, but virtually all products.) We can't impose "differential tariffs" due to the "most favored nation" element of the treaty which requires us to treat ALL member nations identically. That also prohibits from banning imports or taking other steps that would be violative of the most favored nation clause.
