U.S. intelligence officials have lamented the difficulty of tracking down Al Qaeda leader Osama bin Laden. But the hunt for the three warlords has in some ways been even more frustrating, in part because of their often high-profile roles in directing operations against U.S.-led military forces and other Western targets in Afghanistan…

The three warlords are Mullah Mohammed Omar, the former leader of the Taliban government in Afghanistan; Gulbuddin Hekmatyar, an Islamic hard-liner who briefly served as prime minister in the 1990s before ordering his forces to bomb the Taliban-run capital; and Jalaluddin Haqqani, a onetime Taliban Cabinet minister whose tribal group has accounted for some of the most brazen attacks this year.
