When the western world sanctioned Russia they expected Russia to collapse. It didn’t. The first reason is that most of the non-western world didn’t cooperate with the sanctions, but the second is simple: Russia has a food and fuel and mineral surplus.
The world as it stands now is every inter-dependent. The supply networks are dizzyingly complex and a final item like a car is made up of materials and parts extracted, made and assembled in dozens of locations.
The world isn’t always this way: it was like this in the late 19th, but after WWI that changed and the era of free trade ended, collapsing in particular during the Great Depression. The world did not become as “free trade” as it was before WWI again till the early 21st century.
