> The semblance of an international order post world war 2 at least suggested that we as a species were attempting to move toward a better place.
Unfortunately neither Russia, China, Iran (Hamas/Palestine, Hezbollah, Houthis, &c), North Korea, Cuba nor other anti-western actors valued that order and instead have sought to destroy it. The world we live in today and the issues we are seeing are primarily due to their actions. In each circumstance the above list (and there are others) demonstrably took actions under their authoritarian anti-democratic governments or societies to break down the order you value.
