News sites across the western world are at this very moment unanimous in blaming Assad for the attack.
The source of this info seems to be William Hague, who apparently gets the straight skinny directly from George Sabra of the UK-US sponsored Syrian National Coalition.
Therefore this is an obviously impartial verdict coming down the chain of a whole lot of folks with no irons in the fire.
It's almost impossible to imagine that Assad's military brain trust would choose to deploy chemical weapons on the very day that UN chemical weapons inspectors arrive in the country.
The entire "red line" issue is a bit of a red herring to begin with. Why has it been decided, and by whom, that spending a half hour bleeding to death while trying to push your intestines back where they belong after being collateral damage in a Hellfire missile strike is a perfectly acceptable death, but dying in your sleep in a gas attack is a red line, the crossing of which marks a war crime?
But politics being what it is, it looks more and more as though the red-liners will have their way.
The blow-back will come soon enough, and once again the pundits will scratch their collective heads and wonder aloud why "they" hate us.
