Rule #1...
The Government Lies
The Milatary Lies
The War Machine Makers Lie
and men die

Rule #2...
The Polititions Son Won't Go
The Generals Son Won't Go
The War Machine Makers Son Won't Go
but, your son will go

Rule #3...
What if They Gave a War and Nobody Came?
What if the Politician Were Required to Lead the First Charge?
The "What If's" are worthless words of wish's
       When they give a War, you will go to the War
       - or - You will go directly to jail
      Only VIP's sons are born with a
      "Get Out of Jail Free" card in their mouth

Rule #4...
John Wayne is the poster boy of War
John Wayne never went to War
Rah! Rah! Wayne! is truly false Patriotism
Rah! Rah! Wayne! is the Propaganda's Psyche Game

Rule #5...
Know thy Enemy
When you come face to face with the enemy
You find yourself looking at a mirrior image
      He has a family just like you
      He has friends jut like you
      He has dreams just like you
      The enemy is just like you

Is there a Purpose to War?
Beats me, I have never found any legitamte reasons for a war. Every war I have examined the root cause of, started from either greed, ego, stupidity, arrogance and/or a host of other pudden-head reasons.
