At the end of President Barack Obama’s inauguration ceremony, civil rights leader Rev. Joseph Lowery invoked the hope of a day “when nation shall not lift up sword against nation, when tanks will be beaten into tractors.” No one expects such a utopian vision to materialize any time soon. But both Obama and Secretary of State Hillary Clinton have spoken eloquently of the need to emphasize diplomacy over a narrow military agenda. In her confirmation hearing, Clinton stressed the need for “smart power,” perhaps inadvertently echoing Obama’s opposition to the invasion of Iraq as a “dumb war.” Even top U.S. military officials, such as chairman of the Joint Chiefs of Staff Adm. Mike Mullen, have warned against overly militarizing U.S. foreign policy.
