-- Knock out the Taliban's air defenses, tanks, weapons caches, and fuel depots so that its ability to fight a long war is degraded. Done.
-- Bomb dug-in Taliban positions on the northern lines to keep fighters pinned down and weaken morale. Done.
-- Disrupt Al Qaeda's command-and-control system. Unfinished.PHASE TWO OBJECTIVES
-- Begin the ground war. The catch: The Alliance incurs the first significant casualties of the war.
-- Go after bin Laden. The catch: Winter vastly complicates the cave-by-cave search by U.S. and British Special Forces. And commandos are likely to face heavy losses.PHASE THREE OBJECTIVES
-- Replace the Taliban. The catch: Any new government's reign could prove short-lived, as tribal and regional rivalries flare up.
-- Shut down Al Qaeda. The catch: A neutralized bin Laden is elevated to hero status throughout the radical Islamic world; and the U.S. faces pressure to go after other terrorist-friendly regimes, from Iraq to Sudan.
