Oh yes, more of this.

I think having a healthy population is key for defense too, so I'd say NHS spending is also defense spending and should get a slice of that pie

On the one hand, this is possibly dubious in that things that aren't generally considered to be part of defence will be used to inflate our defence spending numbers without actually spending that (i.e. it's just a PR move)

But on the other hand, this could be immensely useful in telling the NIMBYs to fuck right off. What's that, you're opposing infrastructure improvements? Aw, diddums, that's too bad. This is deemed critical for national security, and thus the government can give it approval regardless. Sorry Bernard.
