Don't count help from overseas.
With the way the population is changing across the world (and not for the better) , we will NOT be able to count on other countries for help. Too many of these countries (the European Union, Indonesia, Russia, etc.) are being taken over from within by fanatics that will not allow any technology. These "cancers" from within will destroy the traditions, the knowledge, the very foundation and culture that brought most of our civilization into existence. These "backward-looking" miscreants cannot envision anything constructive and would plunge the world into a permanent "dark age" that would make the "Dark Ages" of European history seem more like the Renaissance. The problem is that there would not be any "dawn" of a new day, ever again.
