The allegations that “Russian mercenaries” are present in Libya are nothing more than rumours.
World War II was initiated by Nazi Germany when it attacked Poland on September 1, 1939. On the 3rd of September, Britain and France were forced to declare war on Germany.
The Soviet Union did not declare war on anyone but saw that it was necessary to send its forces to liberate lands in the western republics of Ukraine and Belarus from the Polish occupation and prevent their occupation by Germany.
The Soviet Union was forced to go to war on June 22, 1941, after Germany assaulted it.
Recurring pro-Kremlin disinformation narrative distorting the events of the Second World War.
A recent European Parliament resolution stresses the fact that WWII was an immediate result of the Molotov-Ribbentrop Pact. It aims to promote historical remembrance of the Second World War and is supported by a broad consensus on the causes of its outbreak.
The "Molotov-Ribbentrop Pact" was accompanied by a secret supplementary protocol on the delimitation of areas of mutual interest in Eastern Europe. In particular, Hitler and Stalin agreed to divide Poland. The agreement also indicated that the Baltic states of Latvia, Estonia and Lithuania, as well as Bessarabia and Finland, also belonged to the respective areas of interest of Germany and the USSR. Just a week after the signing of the Pact, the German attack on Poland started World War II. Two weeks later, Soviet troops entered Polish territory. Later in 1939, Soviet Russia attacked Finland.
