A year ago, 63% said the U.S. did not have a responsibility to do something about fighting in Libya; a nearly identical percentage (64%) now says the U.S. does not have a responsibility to act in Syria. In the current survey, 68% of Republicans and 63% of Democrats say the U.S. does not have a responsibility in this area.

There also is strong opposition to using military options in dealing with Syria. Fully 62% oppose bombing the Syrian military and 63% are against sending arms to anti-Assad groups. Last year, prior to the allied military mission in Libya, 69% opposed arming anti-government rebels and 77% opposed bombing Libyan air defenses.

After the allies launched air strikes against Libya last year, there was modest public support for the military operation; 47% said the airstrikes were the right decision while 36% said they were the wrong decision.
