White House all but sure Syria used chemical weapons – but needs to be sure

Since August, President Obama has laid down use or transfer of Syria’s chemicals weapons as a 'red line.' The White House letter puts the US closer to acknowledging such a line has been crossed.

The US believes with varying degrees of confidence that Syria's regime has used chemical weapons on a small scale, the White House said on Thursday. But it added that President Obama needed 'credible and corroborated' facts before acting on that assessment.

The White House bumped up its confidence Thursday that Syria’s Bashar al-Assad has used chemical weapons against his own people, but it stopped short of issuing a definitive conclusion on what President Obama has said would be a “game-changer” for US policy on Syria.

In a letter to two senators, the White House said US intelligence agencies have assessed “with varying degrees of confidence” that the Assad regime has used chemical weapons on a small scale in the country’s civil war.

The White House says “physiological samples” led to an assessment that the chemical agent sarin was used. But it also cautions that the United States is not certain about the “chain of custody” of the samples that were evaluated, and “so we cannot confirm how the exposure occurred and under what conditions.”

The letter adds that “intelligence assessments alone are not sufficient” and that the US would only act on “credible and corroborated facts that provide us with some degree of certainty” about the use of chemical weapons.

Since last August, Mr. Obama has laid down use or transfer of Syria’s substantial chemicals-weapons stockpile as a “red line,” the crossing of which would trigger a serious US response. The White House letter puts the US closer to acknowledging that the “red line” has been crossed, while maintaining that more facts are needed before the US has the level of certainty required to act.

One of the senators receiving Thursday’s letter, Sen. John McCain (R) of Arizona quickly cast a negative light on the White House position, suggesting to journalists that it was formulated in a manner to allow the president to put off the kind of intervention in Syria that he and other members of Congress favor. Senator McCain told CNN that the letter was crafted to give the president “an out.”

The letter, which was signed by White House legislative affairs director Miguel Rodriguez, was also sent to Sen. Carl Levin (D) of Michigan, chairman of the Senate Armed Services Committee.
