Albuquerque AS President Obama moves to ramp up the United States’ presence in Afghanistan, he might benefit from the lessons learned by one of the C.I.A.’s legends of covert operations, Bill Lair. Mr. Lair ran the C.I.A.’s covert action in the 1960s in Laos, which at its height included 30,000 Hmong tribesmen battling Communist insurgents. I met Bill Lair when he came to the C.I.A.’s training center in Virginia in 2000 to speak at the graduation ceremony for my class of trainees.
