The Soviet Union had not been able to conclude a collective agreement with Great Britain and France against Nazi Germany, notably at the Munich conference in September 1938. In early 1939, the Soviets faced the prospect of resisting Germany`s military expansion in Eastern Europe almost alone and began to seek a change in policy. On May 3, 1939, the Soviet head of state, Joseph Stalin, dismissed The Jewish Foreign Minister Maksim Litvinov and replaced him with Vyacheslav Mikhailovich Molotov, who soon entered into negotiations with the Nazi Foreign Minister, Joachim von Ribbentrop. The Soviets continued to negotiate with Britain and France, but Stalin eventually decided to reach an agreement with Germany. He hoped to keep the Soviet Union at peace with Germany and buy time for the construction of the Soviet military building, greatly weakened by the clean-up of the Red Army officer corps in 1937. The reluctance of Western democracies to oppose Adolf Hitler, with his own unexplained personal taste for the Nazis, also played a role in Stalin`s last election. Hitler, for his part, wanted a non-aggression pact with the Soviet Union so that its armies could invade Poland virtually without resistance, which allowed Germany to manage the troops of France and Great Britain in the West without having to simultaneously fight the Soviet Union on a second front in the East. The final outcome of the German-Soviet negotiations was the non-aggression pact, which datesed to 23 August and was signed by Ribbentrop and Molotov in the presence of Stalin in Moscow. On 16 April 1920, Victor Kopp, the RSFSR Special Representative in Berlin, asked the Ministry of Foreign Affairs if there was “a way to link the German and Red armies to a common war against Poland.”  This was another event at the beginning of military cooperation between the two countries, which ended before the German invasion of the Soviet Union on 22 June 1941. On 17 September, the Soviet Union finally arrived in the Polish territories granted to it by the secret protocol of the Eastern Non-Aggression Pact. As a pretext to justify their action, the Soviets called the collapse of the Second Polish Republic, claiming that they were trying to help the Belarusian and Ukrainian peoples.
The Soviet invasion is generally seen as a direct consequence of the pact, although the revisionist school claims that this was not the case and that the Soviet decision was taken a few weeks later.  The Soviet approach was denounced by Britain and France, but they did not intervene. In an exchange of Polish territories conquered in accordance with the provisions of the protocol, the Red Army and the Wehrmacht have already held a joint military parade in Brest on 17 September; The occupation of the city was then transferred from Germany to Soviet troops.  In the ensuing fighting with the rest of the polish second republic army, the Soviet Union occupied territories that roughly corresponded to its interests, as defined in the additional protocol secret to the Molotov-Ribbentrop Pact. In his speech, Putin questioned whether the Molotov-Ribbentrop pact was the only document signed by a European country with Fascist Germany. “It turns out that`s not the case at all. I`ll just list them, if I can. The declaration on the non-use of violence between Germany and Poland… Signed in 1934. It`s basically a non-aggression pact,” Putin said. On the other hand, Russia sees a direct link between the liberal democratic order and American hegemony, which Moscow more vigorously challenged in 2014.
From a Russian point of view, a new world order will inevitably emerge in the future, based on a stable balance of power and interactions between several centers of power.
