So the question, for Paul Craig Roberts and everyone else is this:  Why would you spend so much on weapons that you would never use?  You wouldn't, I wouldn't and we didn't.  When, not if, when, things get really shitty, and resources are running out and billions are refugees, well, then we will have to do whatever is necessary to secure the last of the shitpile, up to and including nuking a statistically significant portion of the remaining population to keep them from using our oil or water or whatever we want for ourselves.  That's the way it works.  With luck, the asteroid will hit before we get a chance.
