It absolutely is, please understand that I'm not american, and I believe the US Mil. budget is way, way, WAY over the top. But the opposite, not having any of it, would be even stupider. You have the entirety of history to verify the claim, and giving exemples of countries who don't have it but are covered and defended by those who do does not really dispute it.
> Saying that we've gotten research via military funding also disregards how much more research we could get if it weren't redirected through the war bureaucracy.
Sure, if you're willing to forget the nature of what we are.
The possibilities are not "war and war research" or "no war, no war research, all in scientific research". The human nature of what makes armed conflict happen has been there since before there even was a notion of anything close to "research budgets".
