Theres always gunna be war for one reason or another its human nature, we can't live peacefully.

Let's not forget that this era of cooperation and peace in Europe has only been around for about 60 years, virtually nothing in the context of human history. It may seem implausible to us now that the current world order should ever be upturned, just as it seemed utterly implausible to the average citizen of Rome or the Assyrian empire that their world orders would eventually come to and end. I agree that the nation-state paradigm will probably eventually run its course and without nations the question is moot, but war in general I'm inclined to believe will be around as long as we are.

I would love to agree with Akademy on this, but sadly, no. Perhaps the concept of a Nation may blur, but this will not make the problem go away. As borders are broken down, the conflict comes closer to home and can manifest itself in civil-war. We may never be able to overcome this innate rejection of peace in the human-psyche. Please tell me I'm wrong.

Akademy is on point in using the example of the EU. Although the innumerable wars between Europe's societies were certainly a powerful lesson on the need for tolerance, economic and political interreliance, not the lessons of history, are what truly cements Europe into an indivisible, peaceful entity. Similarly, war between individual states in the U.S. is now unimaginable because of the complete political and economic integration that came to pass after the disastrous American Civil War. No matter how sophisticated we imagine ourselves to be, the tribalism of human nature is an inescapable source of conflict. Peace can only be attained by emplacing liberal economic and political institutions that promote interdependence among different societies. Empowering such institutions is obviously extremely difficult, as autocracies still thrive despite the evident superiority of liberal concepts like democracy and free enterprise in creating affluence, individual freedom, and tolerance. Immanuel Kant's democratic peace thesis continues to stand true for a reason. The nation has not been around very long, but it's already greatly diminishing in importance; hopefully in the future the concept of the nation will be obsolete. I like my country, but I nonetheless say good riddance.
