Good point of which I overlooked. However, (as someone earlier in this thread stated), with perfect intelligence and hindsight I am easily on par with General Patton, Napoleon, and Genghis Khan when it comes to military strategy. :)
The film covers the final days from late July 1945 until the Emperor's broadcast of the surrender announcement, but focuses on the last 24 hours up to that announcement. It gives you great insight into the utter depravity of a large faction of the general staff and the risks taken by those who opposed them even with the emperor's backing to agree to surrender.
