Med Music Jinhai Wang thinks that 1937.9.18 invasion of China by Japan inspired the growth and control of Nazes in Germany. Whether that accelerated the time table of WWII to 1939 is a question.  German attacked France, British, Russia, and other nations in EU during 1939-1944. China defensed Japan and Russia defensed Germany, Russia and China protected each other from the attacks of Germany and Japan from two sides . Italy was on the side of German and Japan. Bombing Pearl Harbor by Japan led USA attacking of Germany in EU. USA air force also showed up in the air of China and helping protection of that region that under Japanese attacking. After a big snow, Russia started their big counter-attack of Germany troops, including Tank troops that was inside of Russia. British, France, USA also mounted great counter attack of Germany troops in EU. EU battle was ended in 1945.5, and Germany was divided into West Germany that was under the monitoring of USA, British, and France, and East Germany, which was directed for a not long time under Russia.  After the end of EU battle in 1945.5, Russia Red Army entered China to help against Japan in China. In early of 1945.9., second day after a small island bombing by USA airforce, Japan declared Japan was defeated. The World War II was ended. The 8 years of anti Japanese invasion of China was also ended.  At times, when there were no choice but to defend the independence and freedom of most nations and people, and the choice of each nation, then it had to be for the protection of most people and their freedom.

Eight years of war, how many lives were lost in China? 6 years of World War II, how many lives were lost in the world?  Why to start wars to against other nations?

Thanks for many great comments and supports from many.
