This reader is generalizing from an extrememly small sample: but the idea

is interesting, none the less:

So far history has shown that a totalitarian empire collapses 9 years after
holding Olympic Games in its capital. Interestingly, it appears that since
Germany overdosed (having hosted BOTH Winter and Summer Games in 1936), its
collapse was much more violent and abrupt than that of the USSR. Just some
mathematical analysis… Actually it all started as I was thinking about Red
China being 32 years younger than Soviet Russia and trying to compare modern
China with the USSR 32 years ago. The Olympiad emerged as a really striking
parallel.
