On September 17 the Soviet Union finally entered the Polish territories that had been granted to it by the secret protocol of non-aggression pact from the east. As the pretexts to justify their actions, the Soviets cited the collapse of the Second Polish Republic and they claimed that they were trying to help the Belorussian and Ukrainian people. The Soviet invasion is usually considered direct result of the pact, although the revisionist school contends that this was not the case and that the Soviet decision was taken a few weeks later.[1] The Soviet move was denounced by Britain and France, but they did not intervene.
