It's also a bit a false narrative that systems win or lose: the USSR people decided they wanted to change, and they changed. The system they have now is not exactly the American system, you'll agree, and they're not dead: so what "won" ? KGB-controlled non-communist autocracy, or Liberal Capitalism ? I'd say the first :)

Now what inspire copy from other country, maybe your definition of winning, is probably the second one. But it didn't have to be at the fall of the wall, or the USSR. The problem was always the USSR, but the solution will probably rarely be the US.
