NATO has agreed to take command of the Libyan no-fly zone this weekend, a goal the Obama administration has sought for days.
However, the U.S., France and Britain will still share keeping up the offensive against Libyan dictator Moammar Gadhafi's ground forces and air defense systems, which will make it difficult for the American military to transfer control of the mission.
In the wake of calls by some members of Congress to define the U.S. strategy, the U.S. general in charge of the military operation in Libya defended the administration's actions.
"I don't think you can stand by and have a debate about that end state while he is killing his own people. By that point, it may have become a moot point," Gen. Carter F. Ham told ABC News in an exclusive interview.
Next Tuesday, U.S. Secretary of State Hillary Clinton will travel to London to help coordinate the international coalition action against the North African nation.
The conference will address Libyan crisis, implementation of U.N. Security Council resolutions, and the humanitarian needs of those affected by the conflict.
