What, then, is to be done? We have to begin with the state: as the incarnation of collective interests, collective purposes, and collective goods. If… - Tony Judt

It would seem to follow that the ‘invisible hand’ is not much help when it comes to practical legislation. There are too many areas of life where we cannot be relied upon to advance our collective interests merely by doing what we think is best for each of us. Today, when the market and the free play of private interests so obviously do not come together to collective advantage, we need to know when to intervene.

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?"

This paradox—that a peaceful European settlement was taking shape even as the two Great Powers of the day were arming themselves to the hilt and preparing for the eventuality of a thermonuclear war—was not so bizarre as it might appear. The growing emphasis in US and Soviet strategic thinking on nuclear weapons, and the intercontinental missiles with which to deliver them, released European states from the need to compete in an arena where they could not hope to match the resources of the superpowers, even though central Europe remained the most likely terrain over which any future war might be fought. For this reason, the Cold War in Western Europe was experienced quite differently in these years from the way it was felt in the United States, or indeed in the USSR.
