This anti-war skepticism corresponds to that manifested in recent polls by the American public, even among those who believe that Assad is responsible for the chemical attack.
This allegation is far from established beyond a reasonable doubt, as has been admitted even by Obama's Chief of Staff.
The number of people killed by the sarin attack on August 21 in Syria is disputed. The US cites intelligence reports saying that over 1,400 people died, and the Anti-Assad Syrian Coalition, in Washington to lobby members of Congress to vote in favour of an American intervention in the war, claims the number is even higher.
But in fact only 502 have been confirmed dead.
