Here it comes: Syria
The possible ramifications have not been worked out here, yes CW are abhorrent but so are conventional weapons when used on a civilian population. Before acting here the US and UK leadership need to work out which brand of Islam they want to support. This sectarian conflict will not be solved with western intervention. Islamic peoples want to live under a dictatorship- it suits their mindframe and motivation. I think Iraq would have been better off with Saddam still in power. Controversial i admit.
