Politics Is Part of Torah!

The late Rabbi Shach was criticized for including politics in lectures to his yeshiva students. While there is a chasm between RS and Hyehudi.org on the content, the intent, and many more aspects of those lectures (and more), I don’t find this itself problematic. Politics, like all else, is part of Torah! And many episodes in Mikra, Mishnah, and Gemara are political; how does it matter the protagonists are no longer around?
