A Gallup poll conducted Monday finds more Americans approving than disapproving of the military action against Libya by the United States and other countries.

The March 21 poll was conducted just days after the United States joined other countries in conducting airstrikes against Libya to enforce a United Nations no-fly zone. The U.N. passed a resolution calling for a no-fly zone in response to reports that Libyan President Moammar Gadhafi had attacked Libyan forces opposed to his government.

The 47% of Americans approving of the action against Libya is lower than what Gallup has found when asking about approval of other U.S. military campaigns in the past four decades.

Americans showed the highest level of support for the 2001 military action in Afghanistan that was a response to the 9/11 terror attacks. Americans also widely supported U.S. airstrikes against Iraq in 1993 and the U.S. invasion of Iraq in 2003.
