Your feelings are correct. There will be no more war in about three generations.
It is almost impossible for us to conceive of right now, but ask your great grandchildren and they will say why would anyone go to war? (as in, besides getting people hurt, its stupid on the surface of it because neither sides gets what they want)

Are you old enough to remember records? Our fathers had collections. Our children have a database.

We ARE on the cusp of great things.
