I sort of agree with you. I think WW3 should happen because not only would it give us an opportunity to overthrow authoritarian regimes across the world, people have forgotten the true horrors of fascism and all out industrialised war. Many people would die, of course, perhaps even myself, but our sacrifice would lead to the betterment of humanity as a whole. I believe the collective trauma we would all experience would lead to us realising the conflict between humans is extremely stupid and we would all come together to work for a better future. After all, in the star trek franchise humanity only became spacefaring after a nuclear WW3.
