You know a nation that does have those things other than the US? Switzerland, which is why a lot of people use swiss Francs, even though Switzerland does not have a huge military. People need to stop reading Graber and others who have no economic training and don't understand global balance of payment accounting. Having a large military does not translate into people wanting your currency, otherwise China, North Korea, and Russia would have well used international currencies, rather than being forced to use the currency of their rivals.
