Do you see what's happening in our world? The great nations are clamoring for positions on a slowly sinking ship. Their fighting through proxies has intensified with each passing decade and they wage war in the shadows, by corrupting eachother's leaders and using invisible weapons.
This will not last forever. Eventually, something will snap. The tension will come undone and two nations will enter a struggle which can only have one outcome; that one nation is forced to fight for its existence. We do not live in the world our species evolved in, nor the world that existed when the atomic bombs were dropped. The sophistication and destructive capability of weapons available to our nations exceed the most livid imagination of our forefathers.
This has happened hundreds, thousands of times in the history of our civilization but this time the calculus is being done in an entirely different order of magnitude.
The world as we know is going to become a fantastic memory, and those who see the new world will either shun their very lineage or be reborn a new, unrecognizable species.
