Weird WWIII, considering currently, there’s only two large armed conflicts in motion, and no country outside of Israel, Palestine, Ukraine, or Russia has actually placed boots on the ground in a conflict zone.
Compare this to WWII, where we had: Japan, Russia, Finland, Senegal, India, Bangladesh, Burma, the Phillippines, Germany, the UK, Poland, Hungary, Austria, Ukraine, Estonia, Lithuania, the Netherlands, Denmark, Norway, the US, Australia, New Zealand, Nepal, and probably a dozen other powers and colonial holdings I’m forgetting, all in active combat.
