By a 45% to 31% margin, more Americans favor than oppose the U.S. and its allies taking military action against Syria, if it is confirmed that Syria used chemical weapons against anti-government groups.

Public interest in the Syrian conflict remains low, and nearly a quarter of Americans (23%) have no opinion about the use of military force in Syria.

Nonetheless, the new survey by the Pew Research Center, conducted April 25-28 among 1,003 adults, finds more public willingness to consider the use of force in Syria than did previous surveys that made no mention of the Syrian government’s alleged use of chemical weapons. In December, just 27% then said the U.S. had a responsibility to do something about fighting between the Syrian government and anti-government groups.

The survey finds that just 18% followed news about the charges that Syria used chemical weapons against anti-government groups very closely, which is little changed from interest in the Syrian conflict over the past two years.
