Sometimes it is hard to see when people are joking here.

> Is the US self-sustainable, i.e. can it function totally on its own?

There's a huge question that needs to be answered first then: who would we wage war on?

Oh try harder, consider "The War of Northern Aggression" in the early 1860s.

We currently have a VERY profitable civil war against our own population, "The War on (Some) Drugs".

I feel quite confident the military industrial complex would continue to profit.
