As Politico reports, somewhat ominously:
The Obama administration has concluded there is “high confidence” that Syrian President Bashar Assad used chemical weapons against his own people on Aug. 21, according to an unclassified four-page intelligence estimate released by the White House Friday afternoon.
The report found that the chemical attack included the use of a nerve agent and that it killed 1,429 people, including 426 children…
…“Our intelligence community has carefully reviewed and re-reviewed information regarding this attack and I will tell you it is more than mindful of the Iraq experience,” Secretary of State John Kerry said in a Friday afternoon speech. “We will not repeat that moment.”
Kerry said the United States has a responsibility to act in Syria and needs no approval from other nations.
Kerry also said that the U.S. will make decisions on taking action "on our own timelines," but today's declaration that the evidence is "undeniable" would seem to indicate that "our timeline" may be moving up quickly.
