If your thesis that a country's currency's value was a function of the strength of its military then we should see a clear correlation between strong countries and strong currencies, and weak countries and weak currencies. But we don't, instead currencies values are correlated with the economic strength and trust in the strength and independence of their central banks.
Prime examples are Russia - strong military, one of the top five in the world, but weak currency and Switzerland who has a cute story about citizen soldiers but whose currency is strong way out of proportion to their military strength. Your thesis is facile, sadly easily disproven. -- Charles
