There's a simple and very logical definition of what a "world war" is - it's when international law completely breaks down, and the only way to get back to a semblance of order in international relations is to have the victors of the ensuing shitstorm impose a new set of rules in some sort of grand finale pact. 1945 was clearly that. 1920 with the League of Nations attempted to be that, but failed. Whatever happens after the current turbulence we can be sure that there won't be a UN and NATO and a World Bank at the end. P.S. The first modern world war was the Thirty Year's War.
