We do not buy any oil from Iran, not since the embassy takeover, from what I understand.
90% of all oil from the Gulf is transported by tanker through the Strait of Hormuz.
absolutely correct..we buy no oil from Iran...we could stop Iran cold if the surrounding countries closed the borders,the US and Britain blocked the tankers in the Straits, and all traffic was halted in and out of Iran, freezing all financial transactions with the outside world..it would take about a week for Iran to crack. But the world is essentially too spineless to do that.
