For the first time since the beginning of the Cold War more than 40 years ago, the political determinants of military security in Europe are changing much more quickly than the technological ones. Non-offensive defence is now a more acceptable strategy than it was before, and this book points towards realistic solutions to the problems of excessive dependence on nuclear weapons and/or self-defeating offensive force structures. The ideas examined are especially important for British and American audiences since the Anglo-Saxon countries are the ones most wedded to NATO orthodoxy and therefore the slowest to react to the current wave of change.
