Has the Red Line Been Crossed?

The Weekly Standard reports:

House Intelligence Committee chair Mike Rogers said this morning on CBS that "it is abundantly clear that that red line has been crossed." ...
"I think that it is abundantly clear that that red line has been crossed," said the House Intel chair, about chemical weapons being used in Syria. "There is mounting evidence that it is probable that the Assad regime has used at least a small quantity of chemical weapons during the course of this conflict."

President Obama has maintained that the use of chemical weapons in Syria would cross a red line. But he is not yet willing to say whether chemical weapons were used last week in Syria.

With all due respect to Mr. Rogers, though, the recent chemical weapon attack does not appear to have been by Assad's forces. The Telegraph observes:

Whatever happened last week in the town of Khan al-Assal, west of Aleppo, it achieved something extraordinary in the Syrian civil war: unity among Washington, Moscow and Damascus.

All welcomed the rapid decision by Ban Ki-moon, the United Nations secretary-general, to investigate an alleged chemical attack that reportedly killed 26, including Syrian soldiers.

Unusually, the request for that investigation came from the Syrian regime, which claimed that Islamic jihadist rebels launched a chemical weapons attack. Since then, precious little evidence in any way has come from the area despite an awful lot of diplomatic noise around the world.

However a senior source close to the Syrian Army has given Channel 4 News the first clear account of what he claims is believed to have occurred on Tuesday. He is a trusted and hitherto reliable source who does not wish to be identified.

The Syrian military is said to believe that a home-made locally-manufactured rocket was fired, containing a form of chlorine known as CL17, easily available as a swimming pool cleaner. They claim that the warhead contained a quantity of the gas, dissolved in saline solution.

 Obama's statement, if it can be trusted any more than anything else he says, was premised on Assad being the one to use chemical weapons, not the rebels.
