Inside their own territories we do have instances of mental nuts seizing power and doing violent things, so its just a few bad apples, but for the west its all of its citizens who are violent. if you are talking about history, look at your own.

but any way, i concede defeat to you, go live your fulfilled life & leave the East alone. We don't need you.

in its entire history it has never invaded outside its traditional borders, and it achieved all this without invading or enslaving people. It will continue this way in future too :)
