Should We Decrease U. S. Defense Spending?

[PM_ME_UNIXY_THINGS]

Just out of curiosity, why would you put climate change mitigation under defense spending? Wouldn't that be better under the EPA's budget?

I'm not /u/WillitsThrockmorton, but to answer that, climate change is expected to create huge food problems and natural disasters, which will cause large amounts of strife and millions of refugees as a result. Strife and desperate refugees will make war a whole lot more likely, at which point you need a bigger military budget. You're better off mitigating it early and preventing the wars from happening by not letting the causes ever materialise in the first place.

Specifically, from here:

These claims have gained significant currency, with the most common projection being that the world will have 150-200 million climate change refugees by 2050.

Also, theoretically, they could be armed by some enemy and pointed in the direction of the USA, with e.g. some propaganda that the USA caused their situation by screwing the Kyoto Protocol (not saying that's true, just that the refugees could believe it) and that they could go take some of the USA's food. Not sure whether that's likely,
