That is quite a loaded question. I don't think I can give a valid answer within the limits of a reddit comment, but what I can do is recommend an amazing book called International Communication: Continuity and Change by Daya Kishan Thussu. It doesn't directly answer your question, but it gives you a great background in how all of what you say tie together in the world and what impact it has. It should give you all the knowledge you need to extrapolate your own answer to the question.
