Of which country did Winston Churchill say "It is a riddle, wrapped in a mystery, inside an enigma"?

Still could be said in 2022!

After 2/24/2022 it's clear what it is: a much too large country inhabited by brainwashed, vodka-driven slaves, ruled by mobsters who dream of imposing their sick order to the whole world. A nightmare.

Beware the great consequences of continued human misunderstanding, especially where great powers are squared against each other.
