We are looking at the end of days.
That's what globalization is designed to do. Take the example of just something stupid like metal bearings. If all the metal bearings in the world are made in one city in some 3rd world country solely because a corporation wants to profit from global labor arbitrage, what happens when that one city gets blown up in a war or falls into civil unrest/failed state or anything else? The world suddenly grinds to a halt and implodes. You need way way more redundancy in manufacturing and everything else for overspecialization to not kill everyone at the slightest disturbance.
Take Singapore for instance. They import what, like 100% of their food? You can't be a country if you import 100% of your food. It's a fake country. You cannot be a country while having zero level of autonomy whatsoever. Circumstances like that means they're either all going to die or be taken over by someone else anyway.
