Centenarian George F. Kennan has died. Historically astute readers will know his as the author of the "containment" doctrine, which essentially guided our foreign policy through the Cold War. What most won't know, what I didn't know, is that Kennan felt his strategy significantly overapplied. As he conceived of it, containment was meant to protect a few spots of great national interest, not become a global policy to plug socialism wherever it uncorked. If we'd followed him, then, there would have been no Vietnam, no Bay of Pigs, fewer national embarrassments. It's all quite interesting. So read the LA Times' excellent obituary, it's a history lesson unto itself.
