The thing I find slightly strange in the entire tragedy is the change in attitude since the use in chemical weapons.
Over 100,000 people have died in the conflict so far, why are we less interested in the 99,000 that died prior to the chemical weapons attack? The death of an innocent child is surely equally as reprehensible whether they have been killed by a 'conventional' shell or a chemical weapon.
(I'm reminded of the Billy Connolly sketch from years ago, when he was talking about nuclear weapons vs. those "harmless" conventional weapons!)
We either choose to intervene to protect everyone (regardless of how they were killed) or we choose to keep out of it, but let's not get morally outraged because one side chooses a different way to kill innocent people.
