Intervention in Syria, but not the Congo, will be because of our national interest. Let's be honest and define what those interests are and what path to best achieve them. What are our objectives? An immediate cease-fire enforced from the air? Securing or neutralizing the stockpiles of chemical weapons? Ousting the Assads to exile in Switzerland or trials at The Hague? Supporting a representative government that recognizes Israel's right to exist and stay out of Lebanese politics? Sending a strong message to Iran?
We have options, none of them good, cheap, or risk-free. We should listen to the president as he makes his case and presents his plan. But if we are still not sure, if we are not united in our purpose, don't go.
