I gave an hour-long speech in 2017 at a naval museum about Operation Downfall - the proposed US invasion of the Japanese home islands (that never happened because of atomic bomb usage.)
I put months into research on this topic and I’ve never shared my findings beyond this single speech.
I’m thinking about making it an article and a video, however, it would be a solid 5k words and/or a nearly 40-minute video with some pretty dense military history.
