Wondering if you've heard of Peter Zeihan. In particular you can see his book "The End of the World Is Just the Beginning: Mapping the Collapse of Globalization". He is personally in favor of globalism but he does believe globalism is going away. Some of his reasons why include:

- The US navy no longer has the class of ships to ensure global policing in international waterways. This requires about 700 destroyers and we have about 60ish.

- With the absence of the US navy policing international waters, piracy will increase, which will make long supply chains unstable.

- A majority of countries that participated in globalization by supplying cheap labor essentially had a generational surplus of agrarian labor that moved into cities. This same generation did not have children at replacement levels. Most of these countries are in demographic collapse. China is the best example of this. So essentially they had a one time advantageous ticket to spend and its been spent.

- The United States is natural powerhouse in manufacturing and can produce many things cheaper than many other countries. The only reason manufacturing hasn't entirely returned is due to the sunken cost in other countries.
