Can we agree that Iran and Syria now constitute a single strategic problem? Surely Ali Khamenei, the Iranian supreme leader, thinks so. Otherwise he would not have ordered the Revolutionary Guards to conduct a policy of all-out military, financial, and intelligence support for the Assad regime, combined with the usual deception (various public statements urging Assad to be reasonable and settle his differences with the protesters, a ridiculous fantasy). Khamenei knows that if Assad falls to anything remotely resembling a free, representative government, the consequences for Iran range from severely damaging to fatal.
