NATO and Syria: The Military Option

At today's meeting in Brussels, the leaders of the NATO alliance denounced Syria for shooting down a Turkish jet fighter. Turkey's Prime Minister Erdogan threatened Syria with retaliation and warned against any military approach to the Turkish border. It is the first time that the North Atlantic Conference has opened the door to international military action against Syria's brutal repression of its own people. Would NATO involvement help the Syrian people or just lead to more violence? Would the diplomatic alternative mean sitting down at the table -- not just with Russia, but also Iran?
