In July 1944, a conspiracy by senior German officers including Count (Graf) Claus von Stauffenberg to kill Hitler failed. A bomb left in a bag under the table at the so-called "Wolf's Lair" bunker in East Prussia exploded but Hitler only sustained a burst ear-drum. It probably failed to kill him because another officer in the room moved the bag away from Hitler. Stauffenberg flew to Berlin and claimed Hitler was dead and ordered the arrest of Goebbels, the Minister for Propaganda. Goebbels then rang a hotline to Hitler and proved to the man sent to arrest him that Hitler was still alive. The conspirators and members of their families were rounded up and executed or sent to concentration-camps - including the Desert Fox Erwin Rommel - though historians are divided on his involvement.
My question is as follows:
If the plot had succeeded, would that have meant the end of the war in Europe? Would the 10 million lives lost in the year up to May 1945 have been saved - notably the Jews of Hungary being rounded up around this time. Would Eastern Europe still have been occupied by the Soviet Union and would Germany still have been partitioned? Or would the new leadership have been able to make a separate peace with the Western allies?
