Is the “world-tradeable” aspect so relevant? Nuclear warheads are going to be locally built and would be send in missiles that would also be built in Russia. The PPP argument is that it’s much cheaper to pay a bunch of rocket engineers and nuclear scientists in Russia, in rubles than in Los Alamos, in dollars. Same for all the logistics chain from raw materials to final assembly, upkeep, and maintenance. If your steel is dirt cheap because you’re full of ore and gas is plentiful, and your workers are paid peanuts, then your tanks are going to be cheap, at least for your own use, regardless of how much they cost in another country. So why would PPP be irrelevant in the case of military hardware?
