Sun Tsu ('The Art of War') who was a teacher not only of war but also of life strategy said that in order to maintain peace we must be prepared for war.
You cannot prevent and prepare for war at the same time.
"It is said in some quarters that we are not prepared for war. What is meant by being prepared? Is it meant that we are not ready upon brief notice to put a nation in the field, a nation of men trained to arms? Of course we are not ready to do that. And we shall never be in time of peace so long as we retain our present political principles and institutions."
~Woodrow Wilson, to the joint session of Congress, December 8, 1914
