Secretary of State Hillary Clinton confirmed Thursday that NATO will take over the allied mission in Libya, relieving the U.S. security forces that have so far commanded the mission to establish a no-fly zone. Clinton confirmed that all 28 countries in the alliance—including Turkey, one of the holdouts—had authorized command of establishing a no-fly zone in Libya. She will travel to London next week to coordinate NATO’s strategy. A senior White House official confirmed Thursday that the handover will not take place immediately, comparing it to setting a thermostat, rather than flipping a light switch. The United Arab Emirates announced Thursday that they will send planes to aid the allied mission, joining Qatar as the only two Arab countries aiding in the mission.
