Prime Minister David Cameron told British lawmakers Thursday that there is "no 100 percent certainty about who is responsible" for the apparent mass-chemical weapons attack on suburban Damascus on Aug. 21. Nevertheless, Cameron asserted that "from all the evidence we have," his government, along with the Obama administration, had made the "judgment" that "the regime is responsible and should be held to account." Also just like the Obama administration, however, Cameron's government has yet to explain exactly what the evidence of Assad's culpability is, or where it came from.
