alt Hacker News#1: US military war spending concerns are largely overblown. It's expending what it already has. The spending is mostly on its own internal industry i.e. the US economy (with due respect to broken window fallacy). It arguably makes it all back from the increase in oil prices.
It's a very different thing to fire a $5m missile that you imported vs one that you made domestically with all-domestic components and labor.

Why is it different? If it’s foreign made then you need to export $5 million of stuff to pay for it, so the economic effect should be similar.
Expending what it already has is true but doesn’t really help. It’s not like we’re going to sit here with a reduced stockpile forever. Those munitions will be replaced. The fact that the spending comes after using them rather than before doesn’t change the equation much.
I'd say firing a missile into another country is technically firing finite or hard to acquire resources into another country. All the resources for the new rockets have to be sourced from somewhere and it's not really important where they came from. They are a real cost not some circular funding. It's more or less blowing up big piles of cash that can not easily be replaced.
