Allied air strikes continue to hit Libya– from Tripoli to Benghazi to Misurata. Those strikes are now aimed at Colonel Moammar Gadhafi’s ground forces, tanks and artillery. A British commander said the allies have effectively destroyed Libya’s air defenses. But Gadhafi remains defiant. Earlier this week he appeared on Libyan television and declared, “we will not surrender.” As the sixth day of a U.S. led military mission continues, we get an update on progress, hear why there’s disagreement within the U.S. and among the international community, and discuss the risks associated with a prolonged conflict.
