"What we have done must convince us that Thucydides was right, that peace is better than war not only in being more agreeable but also in being very much more predictable. A plan and policy which offers a good promise of deterring war is therefore by orders of magnitude better in every way than one which depreciates the objective of deterrence in order to improve somewhat the chances of winning."
