> the main objective of the DoD is preserving a general liberal-democratic post-war order, one which persists only because of a balletic balancing of forces.
Objectives are one thing - how much effect they have is a quite different question. Historically there's a long-standing decline in violence; the fall of the Soviet Union, the decline of British dominance, or even the end of the Roman empire are barely a blip on the graph. Is the DoD actually helping, or are they just a rock that keeps tigers away?
> to condemn the DoD as "620 billion going towards killing people" is. . . dumb. Or unconsidered, to be more charitable.
Maybe. If the politicians screw up welfare, the worst that happens is some shysters get some money. The DoD is always going to involve killing people. Hopefully they're a tool that we can use to do more good than harm. But if you don't believe they're being effective - or being used effectively - then all that's left is the killing.
> Remember: it isn't manna from heaven. It's money from income earners.
True, but equally applicable to the DoD
> economies have overcome many revolutions, from iron to industrial, without these programs. Do you have a principled reason why the information age is any different?
Economies survived without these programs, and would do so today. But most people's lives were nasty, brutish, and short. It's worth spending money to improve on that.
