On numerous occasions in the past fifteen years, U.N. peacekeepers have been accused of sexually assaulting or abusing the populations they serve. A Comprehensive Review of peacekeeper misconduct completed in 2005 identified significant problems and recommended numerous changes to address them. The U.S. Army and NATO, in a response to the possibility that their deployed troops will be engaged in or facilitate human trafficking, have enacted new policies intended to remove their troops from the demand for women trafficked for sexual services. The Department of Defense and NATO initiatives are similar to those being considered by the United Nations for preventing sexual misconduct by its peacekeepers. Because the United States, NATO, and the United Nations are all addressing the problems of sexual misconduct by deployed troops, their efforts should be mutually reinforcing. The examples of American and NATO armed forces offer hope that the United Nations will also enact strong measures to prevent future misconduct by its peacekeepers.
