The natural principle of war is to do the most harm to our enemy with the least harm to ourselves and this of course is to be effected by stratagem.

Thus what is of supreme importance in war is to attack the enemy's strategy.

War - An act of violence whose object is to constrain the enemy to accomplish our will.

I do not believe that the men who served in uniform in Vietnam have been given the credit they deserve. It was a difficult war against an unorthodox enemy.

Truth engenders hatred of truth. As soon as it appears it is the enemy.

It is a simple but sometimes forgotten truth that the greatest enemy to present joy and high hopes is the cultivation of retrospective bitterness.

The greatest friend of truth is Time her greatest enemy is Prejudice and her constant companion is Humility.

The truth that is suppressed by friends is the readiest weapon of the enemy.

There are only two people who can tell you the truth about yourself - an enemy who has lost his temper and a friend who loves you dearly.

The innocent and the beautiful have no enemy but time.
