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. But in fact, spheres of influence don't work out very well, certainly not for the victims, and there are always victims.

John Kerry tried to work with the Russians on Syria, and the man was honorable, because he was trying to do the right thing, and frankly, playing a very weak hand, a hand that was weak not because of him, okay. He did the best he could, but I will say this to his enormous credit: he never offered a dirty deal. You can have Ukraine if you only help us out on Syria. Never - he never did that.

The West in its modern form since 1945 is a miracle, and that`s in our American interests. It`s its good that the West is strong and at peace, and we should want more of that, not less.

Our mistakes, blunders, flaws, and shortcomings notwithstanding, the world America made after 1945 and 1989 has enjoyed the longest period of general peace in the west since Roman times, and decades of prosperity.

I think that President George W. Bush was ahead of most of his government, in realizing that Putin was not the person we thought he was.

The Russians are using the tools at their disposal to weaken Western solidarity, to create doubt, to support nationalist parties, just as the old Soviets supported leftist parties. We need a united Western response to this multi-pronged threat.

Putinsim is not necessarily the end state for Russia. Russia has moved in many directions since the early 1980s.
