As far as a Space Force goes, I believe its the stepping stone in the right direction for further expansion into that frontier. As for cyberspace, I agree that there needs to be a condensed oversight. Do you know how many organizations in the IC that deal with cyber security? I can name 5 off the top of my head, mostly because I'm trying to get an internship (DIA pls hire me).
Theres also this weird ven diagram of who ensures the safety of US Nuclear facilities. Is it the Air Force? The DOE? The FPS? All of them?
