I've read more history books than you've had TV dinners, Pops. Countries that "don't last forever" are relics of the ancient world, when there was somewhere else to go when the empire falls. Planet is all full up now. Countries rise and fall in influence, which has happened to us in the last century (up) and is extremely likely to happen to us in the next century (down) if we don't watch ourselves. In extremis, they may change their form of government or be swallowed by a neighbor, which is not terribly likely to happen to us.
I'm sorry to dampen the dramatic hopes of people with an apocalyptic vision and a cellar full of MRE's, but the "cease to exist" option isn't on the table. In fact, it's arguable that global political movement is toward a more American approach (mostly because freedom works to the greatest good of the greatest number), and our biggest danger is letting some other nation out-American us.
Astounding. Someone who actually believes history will now change and countries will last forever. Wow. Show me some evidence, lad, to support your claim. Actual evidence, please.
For some reason, I doubt your claim regarding history books and MREs suck. My IQ is 155 and I am the author of 21 books. Been to 43 countries and travel the globe instructing people, organizations and pro-democracy governments how to stay alive in this new world. I trust you can match that. No? Oh.
You are young and unaccomplished, I suspect, with the latter likely being because you've never been out of your living room and are truly convinced of your superiority even though you you have been nowhere and done nothing to further the cause of freedom. You live in the cyber world where you can hide from the real and strike via key strokes.
Good luck with that.
Wake up and smell the cordite.
You aren't talking about the "American hemisphere" crapola, are you?
