siblings fight with each other kids fight grown-ups fight dogs fight with dogs dogs fight with cats what's my point? the point is fighting/war is an instinct have you watched meerkat manor on discovery channel? that show shows plain and simple the animal instict of war. road rage.. i'm sure every driver has experienced this. having a bad day and someone cuts you off, you go "what the f%#@!! i'm gonna kill that s@#$ b#$*^$!!" grrrrr! and your little car with a 1.5L engine now becomes a weapon of revenge with 300hp under the hoop war in an instinct, but instincts can be suppressed take for example priests who swore chastity. they (or at least most of them haha) are able to suppress their instinct to have sex (i dont think that's healthy though) SO.. if war can be avoided.. that is yet to be seen and only the future can tell

Understanding and respect for different kind of life, religion .....etc

@John Fight is an instinct, right... but I'd translate animal fight into human COMPETITION, not war. Just think of goals, terms, role in evolution and life. In addiction, animals can't be evil...

only love can stop it

trading resources, material and human. hey, royalty used to marry off their kids to retain peace between countries.
