"On the anniversary of the begginning of the Second World War launched by the USSR and Germany, alongside of propaganda graffiti, a huge poster depicting the joint parade of the Wehrmacht and Red Army troops in occupied Brest of Sept. 22, 1939 was put up near the Brest Fortress," Censor.NET reports citing a statement by the members of Charter97.
"The fact of holding the parade as well as the alliance between Hitler and Stalin in 1939 was always hushed up by the Soviet historiography. The incumbent Belarusian government also tries to relegate the truth to the obscure corner replacing it with ideological myths about the 'Great Patriotic War of 1941-1945'. The campaign primarily targets the Russian tourists, the large number of whom do not have a clue that the USSR entered the war not on June 22, 1941, and was not a victim, but an aggressor," the activists said.
According to Wikipedia, German–Soviet military parade in Brest-Litovsk refers to an official ceremony held by the troops of Nazi Germany and the Soviet Union on Sept. 22, 1939, during the invasion of Poland in the city of Brest-Litovsk (or Brześć Litewski, then in the Second Polish Republic, now Brest in Belarus). It marked the withdrawal of German troops to the previously agreed demarcation line and the handover of the city and its fortress to the Soviet Red Army.
