Hello from Cuba. Happy to see this approach, this kind of "deep dive". I have not looked before to this topic, but certainly you connect a lot of points that are enough for me to do my own research and maybe come back to you with a More substancial and informed comment.
Though you aren't interested in democracy, I see that the discussion on this concept is directly connected with the referred hearing. What topics Republicans select and what's the approach followed? Best regards.
