Some people, myself included, advocated foreign intervention in Bosnia and Kosovo while opposing our adventure in Iraq. Sam Moyn might find this inconsistent, but (on this occasion at least) it is the world that is inconsistent, not us. During the Balkan wars individuals’ rights were under ascertainable threat in real time. Outside intervention could make a difference, and it did. This was not the case in Iraq. We should always be suspicious of the invocation of universal “rights” as a cover for sectional interests. But it doesn’t follow from this that talk of rights is “really” always about something else. Sometimes it is, and sometimes it isn’t. How, then, should we adjust our response? Well, there is a serviceable Keynesian answer to that: "When the facts change, I change my mind. What do you do?"

We have entered an age of insecurity—economic insecurity, physical insecurity, political insecurity. The fact that we are largely unaware of this is small comfort: few in 1914 predicted the utter collapse of their world and the economic and political catastrophes that followed. Insecurity breeds fear. And fear—fear of change, fear of decline, fear of strangers and an unfamiliar world—is corroding the trust and interdependence on which civil societies rest.

If Stalin engineered the Prague coup without fully anticipating these consequences, it was not just because he had always planned to enforce his writ in a certain way throughout the bloc. Nor was it because Czechoslovakia mattered much in the grand scheme of things. What happened in Prague—and what was happening at the same time in Germany, where Soviet policy was moving swiftly from stonewalling and disagreement to open confrontation with her former allies—was a return by Stalin to the style and strategy of an earlier era. This shift was driven in general terms by Stalin’s anxiety at his inability to shape European and German affairs as he wished; but also and above all by his growing irritation with Yugoslavia.
