I'm confused about Poland. You have Wojciech Jaruzelski's photo there, but he wasn't the leader of Poland in 1980.
Depending on how you define the "leader" of Poland, I suppose that position could be:
• The Chairman of the Council of State, which in 1980 was held by Henryk Jabłoński (Jaruzelski succeeded him in 1985);
• The First Secretary of the PZPR, which in 1980 was either Edward Gierek or Stanisław Kania (with Jaruzelski succeeding to the position in 1981); or
• The Prime Minister of the Polish People's Republic, which in 1980 was held by Piotr Jaroszewicz, Edward Babiuch, and Józef Pińkowski (Jaruzelski again succeeded to the position in 1981).
