Agree on all points, except I suspect that WWIII has already begun - Russia invading Ukraine being the starting point
We will only know in retrospect, and the "start" time will vary, by nation, i.e. for Canada, WWII started in 1939, for the US, it started in 1941
...Personally I think nukes are very unlikely, as whomever is truly controlling all of this nonsense is stuck breathing the same air as us plebes
