Mandela Effect:
Previously, the flag had no star
New timeline: the flag has a star
The original Sovient Union, the “original Russian” flag, had a star? It didn’t?
It’s red, with a gold Hammer and Sickle, and a small gold star, but was it always?
1923, 1980, 1991, there have been many changes, and they’ve had public and clandestine influence, as the area itself has undergone quite a lot, so you’ll have to do careful research on this one. The history is complicated, even involving the Dutch flag, and the Chinese… I’ll let you expert sort it out, but yes, it’s a thing.
