Points of interest from what I have read so far.
The end of the land grabbing wars as they knew it prior to WWI. I think Roosevelt had a lot to do with this.
Gen Billy Mitchell's, at the infancy of modern flight, prediction that aircraft would play a significant roll in post WWI warfare. That he was ridiculed and laughed at at the time. He went to his grave fighting for an Airforce.
Jimmy Doolittles squadron that had the courage it took to launch B-25s from the deck of an aircraft carrier, in rough weather against all odds, to bomb Tokyo and then try to make it to China, our ally at the time, on fumes. All pilots and crew survived the mission.
The Japanese soldiers really were ruthless, vicious warriors.
We did some bad things too in the name of anger and revenge for Pearl Harbor. How else can you defeat a vicious enemy?
