> Sure it’s bad now,

That's the thing though: it's not bad now!. Not by any historical standard, at least.

For most of our history and prehistory, right up to the past 70 years, stupid warfare has been the rule. Petty tribal disputes, armed insurrections, ethnic cleansing and suppression and random gang violence were absolutely routine for almost everyone even as recently as our great grandparent's lifetimes. Virtually everyone saw violence like this at some point. Now, in most of the world (no, not all of it, but yes: most), pretty much no one does.

And that's important. What we've been doing is working. Don't rock the boat.
