War or death. War against Iran or death of USD. This is what it is all coming down to. US cannot allow one of largest oil producers to sell oil in anything they feel like it even after they were cut off from SWIFT. Watch Syria. It may not have much oil but it is more or less province of Iran. US is trying to do Libya 2.0 there but them pesky Russians are getting in the way. With all the trillions printed recently the only reason why USD is still used as money is oil trade. After hanging Saddam who wanted to get off USD and killing Kaddafi who wanted to create oil producers dinar and looting richest country in Africa Iran is the biggest problem. Syria is Iran but Iran is not Libya.
