Great point; there is also an additional dimension to this. It is impossible to emphasize just how important security is to the blooming of creative financial institutions and highly specialized & sophisticated economies. Its because the US and Europe have created a system where, say, a legal framework exists to get retribution in case of genuine foul play in either country, that we can have sophisticated trading channels. Without the security and stability provided by an overwhelmingly powerful, but mostly reasonable military, we don't have to worry about our trading networks being taken apart at will (basically, eliminate that risk). If that security apparatus ceases to exist, so will the advanced economy that the west has created (which has been slowly expanding, to other nations as well).
This long perspective is hard to ignore. It feels like we are walking the same historical path now. Let's hope things move slowly enough with respect to security that the trading networks stay intact.
e.g. look at https://en.wikipedia.org/wiki/Crisis_of_the_Third_Century. The sophisticated trading network of the Roman empire quickly disintegrated and was one of the principle causes for its eventual demise.
