Stephen F. Cohen: As Russia’s leader, Putin has changed over the years, especially in foreign policy but also at home. His first impulse was toward more free-market reforms, anti-progressive taxes.

On September 11, 2001, he called George and said, Whatever you want, we’re with you. Bush says, Well, I think we’re going to have to go to war in Afghanistan. And Putin said, I can help you. We’ve got major resources and assets in Afghanistan. I even have an army over there called the Northern Alliance. I’ll give it to you! You want overflight? It’s all yours!
