Well I hope that isn't the end of it, as the situation may deteriorate still further. I hope this was a vote against action "now", rather than for all of the future. I have a hard time believing that not intervening is the best course of action, or at least that intervention would have made things any worse than they already are.
The margin of defeat was pretty narrow, so it seems likely that yet more violence in Syria might tip the balance in favour of military action. In my opinion, we've already waited far too long...
