Zeihan has compelling arguments. I like the way he integrates geography, especially knowledge of agricultural, mineral, and transportation advantages some countries have, demography, and economics. He overstates the "demographics is destiny" aspect of his analysis. Japan, for example, is navigating a demographic decline relatively well. China will probably have a more difficult time if only relative to the CCP's ambitions. But China can continue to improve the quality of life for Chinese people if they don't do anything really stupid and end up isolated like Russia.
