SMILE - it's the safest way to spread your cheeks!
Mercenary warriors have been used to supplement armies since the dawn of time.
Only in recent years when weak men have tried to "civilize" the art of war has this become a problem.
No such thing as a "war crime".
The object of war is to kill all of your enemies and anyone that supports them, then stop!
A line from the movie King Author sums it up for me.
Leave no one in your wake whom can ever bear a sword against you.
