Does lifting sanctions on a country that you’re at war with the smart thing to do? Literally helps to fund their enemy.
It is not a zero sum game. Letting the oil through, and thereby preventing the world market from a total tail spin, probably helps the US more than it helps Iran. So is on the surface surprising, but surprisingly rational on second look.


You surely need a lot of oil tankers to sail oil across the Pacific Ocean - because each voyage takes so long. And there needs to be export oil terminals in the US towards Asia, which I assume there isn’t currently, because Asia was supplied by the Middle East.
So a priory doesn’t seem too surprising to me, that there is a price spread.
