Do We Realy Need War?

Can u imagin a world without war cuz i cantbut it would be kool to have a none violent world. but then what would we use to conquer a city then if there was no war and there was no way to make war how would we have a battle or anything

I can vividly imagine a world where lambs will lie with lions. Unfortunately that won't happen for some time.

The military industrial complex has taken hold of power so world peace doesn't have a chance right now. They need war and conflict so they will get it one way or another.
