No I don't think we will be getting World War 3. Nuclear weapons these days pretty much make WW3 an impossibility among powerful nations. The only reason Russia is able to mess with Ukraine is because they have no deterrent. The only reason Israel is able to bomb Lebanon, Iran and Palestine is because they have no deterrent. As long as you have Nukes, there's no World War 3. I know they existed during WW2, but they were in their infancy and if Germany ever made nukes, that could have changed the whole course of the war.
