Obama is mainly just doing to Iran what the American Right wing, including Frum, want done to Iran. But it is that clear, unambiguous policy that is helping drive up prices. The embargo may be causing Iran to export a couple hundred thousand barrels fewer per day than it would otherwise. The embargo, and sabre rattling toward Iran, are driving prices higher.
Frum helped beat the drums for war with Iraq, and maybe he favors another war, this time with Iran. But for him to tell the American people that such unambiguous warmongering would *lower* the price of petroleum is nothing less than a Big Lie.
