I see it the same way—the Iranian regime was always going to blame the protests on America, anyway. It should now be clear that the regime in Iran is nothing like the rational partner that Obama envisioned. When the U.S. took no action after Assad used chemical weapons, the question was always: Did you enforce your red line? And setting a red line invites everyone—friends, foes, cable news pundits, podcasters, your own opposition party—to watch for the moment you blink. But none of these measures will bring down the Iranian regime, which is armed to the teeth and quite experienced in getting around sanctions.
