There's not a single western industrialized nation or state that can be pointed to now as a mask success story. There were a few countries in eastern europe (specifically czechia) that were heralded as a primary reason for controlling covid in the spring.
We now know that this apparent good result was not because of masks, but because of geography. Czechia is ranked #1 in the world in cases / million in the last week and #3 in deaths / million (and its numbers are still climbing). Every single eastern european nation had low cases/deaths in the spring and now all of them are having their first large surge.
It's abundantly clear that cloth masks, as a whole, do not play a major role in how the virus spreads in a country.
