> WW2 was the last big state on state conflict -- that cannot happen again.

Respectfully, the belief that large-scale war was impossible between modern states was prevalent prior to the First World War.

I strongly believe that there will eventually be another large conflict, and that the only reason there hasn't been one to date is because we've managed to maintain the balance between Russian and American interests throughout the Cold War.

The collapse of the Soviet Union marked the beginning of a transitional state, and we've not reached a stable balance of power since.

Perhaps "cannot" was the wrong word choice. "must not" may be more appropriate.

I share your fears and find it terrifying, as that large scale war with the technology that we have today is a profoundly more damaging thing.
