The Ukraine mess is daily looking more like the Spanish Civil War of 1936-1939,a meat grinder that took 500,000 lives.That three-year conflict became a savage proxy war and prelude for the belligerents of WW2.The Ukraine battlefield is proving to be a similar laboratory of death.New lethal weaponry and tactics are introduced,modified-and improved-from drones to guided missles to internet-fed artillery.Likewise, a similar pre-global war lineup of the eventual adversaries is emerging in a preview of a much larger, much scarier war to come.Which will be a nightmarish main attraction,perhapsWW3?
