Most of you know John Garamendi (if you know him at all) as the former California state official who won a special election for Ellen Tauscher's old seat in Congress. But those of us in the business of health wonkery know him as one of our own.

This afternoon, Hillary Clinton gave what I thought was an excellent speech laying out the Obama administration's approach to the world.

Around the time of the November election, John Nagl, a retired Army Colonel, took a helicopter ride across Afghanistan. What he saw below worried him. Nagl, who is 42 with trim brown hair and academic eyeglasses, spent three years in Iraq, including as part of a tank battalion in the Sunni Triangle, where he witnessed brutal combat in the war's worst years. A West Point graduate and Rhodes Scholar, Nagl applied the lessons of his Iraq experience to the Army-Marine Counterinsurgency Field Manual, which he helped write and which was published last year. He currently specializes in the study of war and counterinsurgency at the Center for a New American Security, a center-left Washington think tank, and it is in this capacity that he recently traveled to the Afghan war zone. As his military chopper swooped over high mountain ridges and plunging valleys, he grimly surveyed the size and the inhospitality of the Afghan terrain. Winning in Afghanistan, he realized, would take more than "a little tweak," as he put it to me from back in Washington a few weeks later, when he was still shaking off the gritty "Kabul crud" that afflicts traveler's lungs. It would take time, money, and blood. "It's a doubling of the U.S. commitment," Nagl said. "It's a doubling of the Afghan army, maybe a tripling. It's going to require a tax increase and a bigger army."
