Leaders like Assad are not completely stupid. Why would you gas your own people, with UN inspectors in your country, while you are on the spotlight of the world stage?
If we go to war, this needs to be the last straw. We need to raise hell with mass protests. Even the liberals need to be turned on this monster, they cannot defend his actions anymore.
We all share this eternally evolving present moment- The past and future only exist as inconsequential mental fabrications.
