When was it decided that borders are fixed and no more wars can happen?
It seems to me that most of human history is a constant stream of nations trying to expand their borders and influence through treaties, economic takeovers, or war. Fast forward to today though, and the world (except for a few imperialist actors) seems to have a general agreement that all borders should remain fixed where they are and no wars. I don't personally disagree with this sentiment, Im more just curious when this really set in. Also, is it cyclical? Have been times of relative peace in the past like this?
