The general is responsible for estimating the likelihood of success in applying force to achieve the aims of policy. The general describes both the means necessary for the successful prosecution of war and the ways in which the nation will employ those means. If the policymaker desires ends for which the means he provides are insufficient, the general is responsible for advising the statesman of this incongruence. The statesman must then scale back the ends of policy or mobilize popular passions to provide greater means. If the general remains silent while the statesman commits a nation to war with insufficient means, he shares culpability for the results.

However much it is influenced by passion and probability, war is ultimately an instrument of policy and its conduct is the responsibility of policymakers. War is a social activity undertaken on behalf of the nation; Augustine counsels us that the only purpose of war is to achieve a better peace. The choice of making war to achieve a better peace is inherently a value judgment in which the statesman must decide those interests and beliefs worth killing and dying for. The military man is no better qualified than the common citizen to make such judgments. He must therefore confine his input to his area of expertise — the estimation of strategic probabilities.

The correct estimation of strategic possibilities can be further subdivided into the preparation for war and the conduct of war. Preparation for war consists in the raising, arming, equipping and training of forces. The conduct of war consists of both planning for the use of those forces and directing those forces in operations. To prepare forces for war, the general must visualize the conditions of future combat. To raise military forces properly, the general must visualize the quality and quantity of forces needed in the next war. To arm and equip military forces properly, the general must visualize the materiel requirements of future engagements. To train military forces properly, the general must visualize the human demands on future battlefields, and replicate those conditions in peacetime exercises.

Second, America's generals failed to estimate correctly both the means and the ways necessary to achieve the aims of policy prior to beginning the war in Iraq. Finally, America's generals did not provide Congress and the public with an accurate assessment of the conflict in Iraq.
