* ENDS AND MEANS No country can be really well prepared for modern war unless it is governed by a tyrant, at the head of a highly trained and perfectly obedient bureaucracy.) I have said that a country which proposes to make use of modern war as an instrument of policy must possess a highly centralized, all-powerful executive.
