I'm assuming you don't mean communism? Because even in the book he is fairly down on communism/socialism. It seemed to me the more likely (and unpleasant) hypothesis is that war/nationalism generates growth like nothing else. When the threat of war looms and patriotism is high, government investment in technology and society is also high, and corporations are more likely to be invested in their home country rather than spreading across international boundaries looking for the best ROI. And the rapid succession of WWI/WWII/Cold War basically ensured that environment existed for decades.
