Except Iran isn't stopping
Except Iran isn't stopping oil production or export, they're just shifting it away from all of the NATO-aligned and Israeli-attached countries who're imposing sanctions and warmongering for no reason.
Iran is continuing exports to Russia, China, etc. Both of those countries have made military moves to stop any attempt by the U.S. to blockade Iran's access to the Gulf.
President Obama and his pundits are playing with WWIII with this asinine insistence that we go to war with Iran.
