(CNN) -- On Saturday, the "let's make ourselves feel better" club will convene in Geneva to try to figure out what to do about Syria. The motives of those gathering in Geneva at the invitation of U.N. Special Envoy Kofi Annan -- the five permanent members of the U.N. Security Council (United States, France, China, Britain and Russia), plus Turkey and a number of Arab league members including Iraq and Qatar -- are well-intentioned. Their concern over the continued killing, more than 12,000 dead with thousands more wounded and imprisoned, is understandable. But sadly, the results of the Geneva meeting, even with some added wind at its back (the Turks are madder than ever at Syria for downing a Turkish reconnaissance plane earlier this week), are not likely to produce much new.
