Hard times are ahead if nations start to care only about their best interest and not about what is the best interest of the whole world.
Then globalization died a second time with the Russia’s war in Ukraine, with the emergence of BRICS and the consequences of sanctions and the breakdown of the global monetary system.
Globalization died when the small minded monster Republicans had been farming for decades escaped its talk radio cage and found Trump. Trump (and his loser-mentality enablers) saw systems they didn't understand, and more irritatingly other parties who wouldn't just lap up shit as they were bossed around, and inferred this meant the US must have been getting a poor deal instead of an awesome one. (BuT tHE dEbT!!1!)
Pax Americana is over, US is no longer capable of dictating globalization to the rest of the world, why? Because many countries has caught up.
If the US weren't still some kind of world leader, USD would be in the toilet as other countries would have dropped most of their USD holdings. The current regime seems to be doing their best to make that happen, whether for cryptocurrencies, foreign agents, or just simple-minded looting.
I'm an American libertarian. It's not Democrat versus Republican. It's conservative versus neofascist/patrimonialist.
