For three generations, the badge of the Soviet revolution meant poverty, slavery, torture and death. It adorned the caps of the chekas who came in the night. It opened and closed the propaganda films which hid the famines. It advertised the people's courts where victims of purges and show-trials were condemned. It fluttered over the re-education camps and the gulags. For hundreds of millions of Europeans, it was a symbol of foreign occupation. Hungary, Lithuania and Moldova have banned its use, and various former communist countries want it to be treated in the same way as Nazi insignia.
The hammer and sickle was used to crush humanity and here it sits at the top. The cross to hammer+sickle ratio is 3 to 5. It would have been more honest if the symbols formed a swatsika instead of a star.
