Realism as a foreign policy doctrine means basically you don't care about values; you consider them a luxury, and it leads to a kind of acquiescence in spheres of influence. Now, spheres of influence sound good if you're a graduate student, or a certain kind of - an academic with a certain habit of mind.

Russia comes from a place of deep resentment against the West, in general, and the United States in particular. They are rapacious, because they want back as much of their empire as they can grab. And we need to resist that. At the same time, we should be able to look for areas of common interest.
