"Know the enemy and know yourself in a hundred battles you will never be in peril. 

When you are ignorant of the enemy but know yourself, your chances of winning or losing are equal. 

If ignorant both of your enemy and of yourself, you are certain in every battle to be in peril."

                     - Sun Tzu, Art of War

What is not stated in the Art of War?

Know the Holy Spirit.

Know karma.

Know how things outside the mundane would actually work.  

Abuse of power is not power; a terrorist (tripping on power) does not have real power or standing with the world.

Anyone can cause harm and destruction.  

Not everyone can inspire peace and prosperity.

“So in war, the way is to avoid what is strong, and strike at what is weak.”*

Are you sure you know who is strong and who is weak?

Who are the friends you keep?

                     

*Sun Tzu, Art of War
