Being detached or incurious about what our commanders are experiencing makes it hard to craft a winning strategy.

Mr. Obama’s predecessor faced a similar situation: a war that was grinding on, pressure to withdraw troops, and conflicting advice—including from some who saw the war as unwinnable. But George W. Bush talked to generals on the ground every week or two, which gave him a window into what was happening and insights into how his commanders thought. That helped him judge their recommendations on strategy.

Mr. Obama’s hands-off approach to the war seems to fit his governing style. Over the past year, he outsourced writing the stimulus package to House Appropriations Committee Chairman David Obey, washed his hands of Attorney General Eric Holder’s decision to reinvestigate CIA interrogators, and hasn’t offered a detailed health-care plan.
