You might want to add one (or more) of Peter Zeihan's books to the list. He does a good job laying out how geographic features - somewhat modified by technology - determine what kind of society can grow there. Then he brings in the post-WWII Bretton Woods accords (basically, the US starts globalism by both guaranteeing the safety of every nation's international-water trade and opens its own markets). This was a necessity at the time for the US, primarily to counter a growing Soviet sphere of influence but also because our oil was coming from the Middle East / Persia and our industrial base was pretty much the only one left standing. Remove those accords, and things fall apart.

He's a good analyst (used to be head of that department at Stratfor) but he definitely has blind spots - mostly around the lower quartile of the population, their income, debt load, rents, etc. His focus is more towards shareholder and military presentations.

FWIW, I was a Stratfor reader for a number of years when Zeihan was there. They were usually fairly prescient — but in a “this will affect stock prices / international relations” or “war could start if these things happen” kind of way.

But it's fascinating reading - part from seeing just how intertwined geography and politics are and part from understanding what might be about to happen as the US, that no longer has much reason to support the global order out of its own pocket, gradually (best case) withdraws.

[edit] I’d start with his 2014 ‘Accidental Superpower’. The first half of the book has a particularly good intro to Geopolitics (how an interplay of geologic features plus tech advances offers advantages — or not — to the people living there). [/edit]
