I agree with you on the keeping politics away from sport idea.
But I think that the Olympics more so than any other tournament is a political event as much as it is about sport. Here's my reason:
I've always thought of the Olympics as a Sagittarian thing, that it has much to owe to Jupiter. Firstly it's the biggest event, gets maximum media coverage all over the world, that's pretty Jupiter. Then you've got the sacred Olympic flame - Sagittarius again, which is brought every time from a certain mountain in Greece.
Jupiter makes these games not just the biggest and best, and a great media show, but because of that planet, there must be power-politics. I don't doubt that it has always been used for political ends... the most blatant would have been in 1936 in Germany.
But the Uranus -Mars link up is still right for the natural disasters that you've ascribed to them, more so because that is a separating aspect, describing something that has already happened. The applying Mars square is to Pluto.
....
Part of the greatness of the Olympics is that all astrological influences are covered, with so many different sports and so many different skills.
