Jocko podcast is generally apolitical and deals mostly with war and leadership, sometimes he even reads and comments on army and marine corps publications

IMO the best introduction to him would be the Dick Thompson podcasts 204-205-206

Exciting war stories, on-the-ground leadership lessons, and then going into personality psychology research

edit: Jocko is a machine and he has thousands of hours of content, all of which you can find insights and lessons from
