Re number 6. I’m not convinced the zionist differences have as much to do with an understanding of history, as much to an ideological difference. It’s a bit insulting to say that if the chazon ish, or the Brisker Rav, or the Satmar Rav had understood history they’d have been zionists.
Each of your examples HAD a derech (at least for 2/3, the CI & Satmer Rov, I can’t speak for Brisker Rov) due to their understanding of history. Satmer Rov was an isolationist, and the CI came to a compromise with Ben Gurion.
