"U.N. has testimony that Syrian rebels used sarin gas...."

Reuters reports:

"This was use on the part of the opposition, the rebels, not by the government authorities," [said commission member Carla Del Ponte]....

President Bashar al-Assad's government and the rebels accuse each another of carrying out three chemical weapon attacks....

President Barack Obama last year declared that the use or deployment of chemical weapons by Assad would cross a "red line."

There's a lot of motivation to lie here. One side used the gas and accused the other side of doing it. Which side was more motivated to use this tactic? The rebels. No? The "red line" announcement created an opportunity for them. On the other hand, that seems so obvious that the opportunity for Assad appears. He can credibly claim they took advantage of the obvious opportunity.

What a mistake to set the red line at something the rebels could do!
