Seems like Iran is going after this for the long haul. If it is true they are dumping their oil rather than shutting off their wells, it seems likely to be effective. Why? because it not only buys more time but the ecological disaster is sure to push the world toward a quicker solution that may conflict with the goals of Trump (though they too are a moving target). This throws out the idea of a checkmate that some were heralding if Iran ran out of container ships for their oil. Because the chess board just expanded with Iran having a move to just dump oil into the sea. For those that are unaware the Iranian wells may not be able to restart if they stop pumping, so they have to put the oil somewhere or risk losing millions of barrels in future production. Sure the USA could bomb these fields but it would mean higher world prices for a far longer time.
While the U.S. has higher prices of gas, many might fail to realize that some Asian nations which depend heavily on Middle East oil and LPG are as little as two months from running out of gasoline entirely, though some supply is now moving from Russia. Such shortages will put enormous pressure on the U.S. and Iran and will result in a global slowdown not from prices but from some nations having severe shortages.
The question is will Trump wait if he knows the pressure on Iran is not as strong as he suspected? It seems that if he wants the list of demands he is going to have to speed up the timeline for troops on the ground rather than slow play toward a diplomatic solution. Iran is a government infused with religion making it far less likely to capitulate through severe hardship or diplomacy. If other nations do have to ration gas. (I have already heard of propane being allowed to be filled to 50% in at least one nation, India for instance is keeping track of how often a household fills an LPG tank, and requiring 25 to 40 days for households and giving only 70% of normal for commercial applications.) Are these severe economic and energy consequences worldwide going to used to blame Iran the U.S. or both?
A scary political solution that a few are mentioning would be a tradeoff against Taiwan to persuade China to help with Iran. Would the U.S. ban the sale of weapons or take other steps after the election, to barter against Taiwan for help in Iran? Kissinger himself traded concessions on Taiwan for Chinese help in ending the Vietnam war.
Few might know too that China controls some of the most critical elements used to manufacture U.S. missiles.

So a more important conflict than some might suppose that the whole world is watching. Hoping we all take time to pray for peace and good policies that can last into the future according to God's will.
