Russia allows Syria to give-up her chemical weapons, because this was the only way to prevent a US military strike. Tomahawk missiles would change the geography in Syria. The aftermath for Assad would have been devastating. Face it, Putin's investment in Syria was always risky. We know, Russia has no quandary about chemical weapons. The is a cold calculation for Putin... a defanged Assad is better then losing a warm Mediterranean port or Syria as a client state. Lucky for Putin, Obama is not George W... the village idiot.
