@Jim - Can you offer a military option for Syria that conclusively improves things? Can you, hand on heart, really say that the evidence of Iraq proves the benefit of military adventures by the US and the UK? We cannot impose an external military solution on a civil war.
There is something particularly ghastly about how indiscriminate chemical and biological weapons can be it is true,especially for preceding generations who may have had first hand evidence from the first and second world wars as to the effects of mustard gas and the like.
And one of the most powerful and moving bits of poetry I ever read was from Wilfred Owen and his poem Dulce et Decorum Est - A poem that rid me of any youthful delusions I might have had as to the honour or glory of war;
"GAS! Gas! Quick, boys!-- An ecstasy of fumbling,
Fitting the clumsy helmets just in time;
But someone still was yelling out and stumbling
And floundering like a man in fire or lime.--
Dim, through the misty panes and thick green light
As under a green sea, I saw him drowning.
In all my dreams, before my helpless sight,
He plunges at me, guttering, choking, drowning.
If in some smothering dreams you too could pace
Behind the wagon that we flung him in,
And watch the white eyes writhing in his face,
His hanging face, like a devil's sick of sin;
If you could hear, at every jolt, the blood
Come gargling from the froth-corrupted lungs,
Obscene as cancer, bitter as the cud
Of vile, incurable sores on innocent tongues,--
My friend, you would not tell with such high zest
To children ardent for some desperate glory,
The old Lie: Dulce et decorum est
Pro patria mori"

But really - how much worse are such weapons than nuclear strikes, or white phosphorus /napalm, or the toxic after effects of using uranium depleted shells? Some evidence to show a much higher rate of birth defects in fellujah as part of the after-effects of the US use of such weaponry, to say nothing of the generational effects of radioactive exposure in Japan following the deployment of nuclear bombs by the US.
So my question is - Hundreds dead, thousands poisoned it is alleged, in Syria. But set that against the backdrop of 100s of thousands of dead and injured from the civil war over the last couple of years. Why should chemical weapon deployment, obscene as they are, be the trigger for western military intervention?
