The Associated Press published this:
“U.S. intelligence agencies did not detect the Syrian regime readying a massive chemical weapons attack in the days ahead of the strike, only piecing together what had happened after the fact, U.S. officials say.
The spokesman for the director of national intelligence confirmed that U.S. intelligence did not detect the massive chemical weapons attack beforehand.”

Shades of the Horrific 9/11 intelligence failure. I look to the top. The grunts in the field, scanning communications or dressing and acting as the locals while trying to ferret out secrets of impending strikes are to be always held in great respect. But who is the Unite States administration taking to task for this latest failure? They saw hints and communications indicating movement with the chemical weapons but nobody sitting at a command desk in the intelligence community figured out it was worth bothering about.

Did Israeli intelligence have the Assad intentions figured out in advance and was the admonition passed on?
I bet it was, and promptly assessed and ignored.

There has been some public discussion about my suggestion that the Assad brother who commanded the military unit that fired the Saran gas into the civilian area should be taken out of Syria and sent to the international Human Rights court in the Hague as a war criminal. Someone suggested going after Bashar himself. I say no, the taking of the brother will send the message that Bashar may follow, and it will drive him to a negotiating table.
