A major difference, IMHO, is the abandonment of the rules-based, rights-based, international order. Within it, international war (as opposed to civil war) was nearly impossible - it hardly existed for generations. While you need to prepare for the worst, you need to work for the best, for progress, like so many generations before us in much more difficult circumstances. Preparing for warfare doesn't mean accepting it; we must also work for freedom, including a just peace. It doesn't happen without work.

Again in this era, reactionary and nationalist messaging has dominated and somehow, despite generations of extraordinary success, despite being born into it and seeing its success and superiority, many/most think such an order is infeasible or even undesireable. At the same time, I've seen American leaders in the military industry advocate for becoming accustomed to mass destruction and death.

And shockingly, even the experts and practioners abandoned it and at nearly the height of its success. It's as if a messaging campaign insisted cloud computing was impossible and absurd, and so everyone just stopped using what was obviously working. For the rules- and rights-based order, yes there were outliers and setbacks and threats; that's life. But the entire free, wealthy, industrialized world subscribed, and were untouchably allied, free, safe and prosperous. Now, having abandoned it, all those things have diminished.

What's missing is not acceptance of warfare but ultimate commitment and work for freedom and peace.
