A new poll finds a majority of Americans don't believe the U.S. has a responsibility to do something about the fighting in Syria. Most Americans also remain opposed to sending arms to anti-government forces in Syria.

The latest national survey by the Pew Research Center for the People & the Press, conducted Dec. 5-9 among 1,503 adults, also finds little change in sympathy in the conflict between Israel and the Palestinians: 50 percent say they sympathize more with Israel while just 10 percent sympathize more with Palestinians.

Only 27 percent of respondents said the U.S. has a responsibility to do something about the fighting in Syria; more than twice as many -- 63 percent -- say it does not. The views are virtually unchanged from March -- even as the violence has continued.

Just 24 percent favor the U.S. and allies sending arms and military supplies to anti-government groups in Syria, while 65 percent are opposed. The opposition crosses party lines: More than 60 percent of Republicans, Democrats and independents say the U.S. does not have a responsibility to do something about the fighting in Syria, and all partisan groups also oppose arming anti-government groups.
