There is no doubt that a lot has been misspent, trillions almost certainly but let's not be naive and say that it could have magically been spent on "better more sensible things" by the same people who misspent it in the first place (congress) and second let's all appreciate that perhaps 1 or 2 trillion a year, perhaps more, is the cost of western civilization not being immediately stomped out by very bad people like nazi china.
