Yeah, if we cut back a bit on the war crimes we could easily fund both more moon missions and cool science, as well as a shit ton of great programs to help people with the basics like food and rent and health care.
We still should cut down (ideally to zero) on war crimes, crimes against humanity, and crimes against peace, but the reason is because those things are unqualified evil on their own, not because doing so is necessary to fund healthcare and other priorities, which it very much is not.
Now war. They think that's worth it, even if it's also bad.
