It seems to me there is so far a complete lack of evidence against the regime for the recent chemical weapons attack near Damascus. What is happening at the moment reminds me a lot of the events that lead to the invasion in Iraq, though I doubt this is going to lead to an actual invasion. But I fail to see what good a US or UK drive-by cruise missile shooting attack would do, as it's unlikely to bring the war to an end, in fact it would probably make it longer. They would have to put soldiers on the ground and have a proper invasion to end the war. Also, supporting "the opposition" doesn't seem like a good idea either, as the islamist contingent appears to be significant.
