Well, I think that Richard Haass, Director of Policy Planning for the State Department, had the same book, because in early 2002 he is quoted as saying "Sovereignty entails obligations. One is not to massacre your own people. Another is not to support terrorism in any way. If a government fails to meet these obligations, then it forfeits some of the normal advantages of sovereignty, including the right to be left alone inside your own territory. Other governments...have the right to intervene. In the case of terrorism, this can lead to a right of preventative, or peremptory, self defense. You essentially can act in anticipation if you have grounds to think it's a question of when, and not if, you're going to be attacked."
So...in the mid-1970's, it was lowbrow British humor. Now it's official foreign policy.
Just so we're clear.
