Stephen Cohen, a professor of Russian History at New York University, sees two pivotal moments that have undermined US/Russia relations in the last two decades. The first was a promise made by George H. W. Bush that after Germany's unification, NATO wouldn't move further east. That promise was broken and today NATO knocks on Russia's doorstep with only a few post-Soviet states--Ukraine, Georgia, and Belarus--remaining beyond its orbit.
