According to the findings of the secret protocol of the pact, in the first phase of World War II the Soviet Union acted de facto as an ally of the Nazi Third Reich. The joint division of Poland into which the Red Army entered just over two weeks after the German troops, in breach of the existing non-aggression pact and the Lithuanian Protocol, was only an overture for further cooperation. In exchange for supplying the Third Reich with strategic raw materials, the USSR gained a free hand to hold a trial with the neighbouring independent states. The scenario was typical for Soviet expansion. Both in the areas of eastern Poland occupied in September 1939 and annexed in June 1940, the three Baltic republics - Lithuania, Latvia and Estonia - convened under the bayonets of the Red Army and controlled by the agency of the People's Assembly, they themselves proposed joining the Soviet Union, to which, of course, generously expressed their consent. Romania was forced, by a major military demonstration, to "voluntarily" hand over the border areas of Bessarabia and North Bukovina. Only Finland is heroically defending itself in the so-called 'war on terror'. The Winter War of the turn of 1939 and 1940 resisted Soviet aggression, but the maintenance of independence was bought by serious territorial losses.
In the areas annexed in 1939-1940, the regulations of the Soviet Union were introduced from time to time. Villages were mercilessly collectivized, production plants were nationalized, and the resistant or only suspect counter-revolutionary population was persecuted by arrests, murders or deportations deep into the USSR. This was the fate of 18 thousand Lithuanians, 15 thousand Latvians, 10 thousand Estonians and nearly half a million Poles, who were deported to Siberia and Kazakhstan in four great deportations.
