> there is no good reason for the U.S. to maintain such a military so giant that it requires massive, counterproductive subsidies to maintain just in-case we need to engage in a massive war.

Investing in the military is nothing like buying more computing capacity on AWS. It's not as flexible as you imagine it to be. By the time war begins, it can be too late. Afghanistan may have been a mistake but other wars were not.

Additionally, federal defense spending as a share of GDP has fallen gradually since WWII and the Cold War. The past couple decades have been our lowest levels since the 1930s.

Finally, if you were to make substantial cuts to our military, the world and our adversaries would take notice, and we don't want the consequences of that. It's hard to grasp how much of the world's geopolitics is altered by that defense budget the American public views as 'going to waste.'

What war? The U.S. is invulnerable to invasion. The only conflicts that the U.S. would possibly need such a massive global military for would be foreign wars to maintain its world dominance (e.g. containing China, proxy wars, etc.), which I contend are pointless and destructive. I disagree with your implicit premise that the U.S. has to be the global hegemon - it does not have to be, especially when the most urgent geopolitical issue is climate change. Who is “top dog” and how their military is going to fuel their tanks doesn’t matter when the entire world is facing environmental catastrophe.

I’m glad our spending levels are apparently as low as they’ve been since the 1930s, but I’m not sure how that is relevant to the U.S. military’s fuel usage and carbon emissions, which are almost certainly higher than in the 1930s.

The consequences being, I assume, the end of U.S. hegemony?

The Titanic is unsinkable!

Pointless and destructive won't stop them.

It doesn't have to be but someone will take it's place and they'll do so with all the same fossil fuel powered war machine because that's the best way to maintain power.

>Who is “top dog” and how their military is going to fuel their tanks doesn’t matter when the entire world is facing environmental catastrophe.

You're letting perfect be the enemy of good. There is nothing that the US (or anyone) can do to stop the manufacture and usage of the most advanced weapons of war available which have a massive carbon footprint.

The sooner you come to the conclusion that _somebody_ is going to do it the sooner you can ask the real question of who would you rather it be.

This doesn’t engage with my point. How many nations with nuclear arsenals and a large ocean on either side have been invaded? It isn’t a likely occurrence, and definitely not one worth subsidizing the war industries for decades in preparation for. It makes no strategic sense for another nation to attempt. Why pretend this is the reason we are doing all of this?

> Pointless and destructive won't stop them.

We agree here. My point is that what they are doing is bad, not that they won’t do it anyway. Of course the U.S. military will continue to try and keep the U.S. hegemony alive and continue expending precious resources to do so.

> There is nothing that the US (or anyone) can do to stop the manufacture and usage of the most advanced weapons of war available which have a massive carbon footprint.

I disagree. The U.S. is one of the largest manufacturers and exporters of military equipment, including jets and tanks. If we stopped making and selling them, we could make an impact on emissions. Sure, other people would likely increase their production, but that doesn’t mean the U.S. has to contribute or provide its technical expertise/resources.

> The sooner you come to the conclusion that _somebody_ is going to do it the sooner you can ask the real question of who would you rather it be.

I think this is a weak argument. This is a lot like the Onceler’s line from the Lorax: “If I didn’t do it then someone else would!”, which may be true, but does not mean you have to continue the current path. The U.S. military could commit to ending its foreign wars and reducing its emissions massively if it wanted to, but it does not.
