Serious war may look different from the past of nation-state wars. We're living through the emergence of network states. Given how the Internet enables non-tangible property (I.e., domain names that one can use to build businesses, associations, non-profits; bitcoin, Ethereum, and other crypto-projects) through communications protocols and cryptographic mathematics, its no longer necessary to wage physical war to gain an advantage. Thus we see a massive rise in persistent threat actors, which could be world war three already happening, but we don't recognize it yet because we're used to observing nation-state wars, not network state wars. Perhaps the modern age of nation state dominance ran from the Peace of Westphalia to 1989, the fall of the Berlin Wall and the design of the World-Wide-Web by Berners-Lee.
