I don't think OP is talking about a specific war, but the overall cost to maintain such a capability and project force all over the world. At least that is what I perceive when people lament about lack of healthcare.

The United States military budget is now 1.5 trillion dollars per year.

Sure, we could just not have a military and hold hands with Russia and China and everyone else.

We wouldn't need healthcare.

We'd just be dead.

Of course it might cost a lot less if we didn't need to pay for unprovoked attacks on countries like Venezuela and Iran.

What if they didnt try to kill us tho? What if the world is so interconnected now, that we actually could hold hands - especially if we already had those asteroids already at the Lagrange points - if we were "post-scarcity" as a species, what would be worth fighting over?

We absolutely can, and will, go get those asteroids.
