Prior to US envolvement, there were TWO wars; a European War & an Asian War. The Asian war started when Japan invaded China in 1931 or 1937, which ever historians wish to use. The European war started when Britain (and France) declared war on Germany when they entered Poland in September 1939. The war became GLOBAL on December 7, 1941 when Pearl Harbor was bombed. Hopefully, today's generation of historians will correct WW2 history as it actually happened. And not the way the British historians want WW2 to be remembered.
