Sort of... But he's right too. We're endorsing chemical weapons via silence, there's no denying that.
I don't see what the problem with that is, though.
There's this utter myth about warfare that runs through all our fiction and all our politics that there is good guys and bad guys in warfare. And you can march in, kill the bad guys and improve the situation.
And you just can't. A humanistic war is an oxymoron. This superhero myth of flying in, hitting assadd and then flying back out to the sound of cheers is pure fiction. Wars are expensive, messy, bloody, create problems and aren't over til generations after the fighting stops.
I'm not a pacifist by any means (I'm probably the only person left in this country to still think we were right to get involved in afghanistan and iraq) but sensible countries don't fight a war over idealistic purposes. You only fight a war if it improves your countries security and this doesn't.
You went us to police the world then after syria we'll have to hit burma and north korea and somalia and uganda and the congo and everywhere else where people are being killed in their thousands.
Western meddling is not the answer to every problem. Soemtimes we should just let the bastards kill each other because frnakly it ain't our buisness to get involved and we have better things to spend the money on.
