Problem: As early as late 1919 the leader of Russia's new Bolshevik government, Vladimir Lenin, inspired by the Red Army's civil-war victories over White Russian anti-communist forces and their Western allies, began to see the future of the revolution with greater optimism. The Bolsheviks proclaimed the need for the dictatorship of the proletariat, and agitated for a worldwide Communist community. They had an avowed intent to link the revolution in Russia with an expected revolution in Germany and to assist other Communist movements in Western Europe; Poland was the geographical bridge that the Red Army would have to cross to provide direct physical support in the West.Lenin aimed to regain control of the territories abandoned by Russia in the Brest-Litovsk Treaty of March 1918, to infiltrate the borderlands, to set up Soviet governments there as well as in Poland, and to reach Germany - where he expected a Socialist revolution to break out. He believed that Soviet Russia could not survive without the support of a socialist Germany. By the end of the summer of 1919 the Soviets had taken over most of Ukraine, driving the Ukrainian Directorate from Kiev. In February 1919 they also set up a Lithuanian-Belorussian Republic . This government was very unpopular due to terror and the collection of food and goods for the army. Officially, however, the Soviet Government denied charges of trying to invade Europe. As Polish-Soviet fighting progressed, particularly around the time Poland's Kiev Offensive had been repelled in June 1920, the Soviet policy-makers, including Lenin, increasingly saw the war as a real opportunity to spread the revolution westwards. Historian Richard Pipes noted that before the Kiev Offensive, the Soviets had prepared for their own strike against Poland.

Problem: After repelling the Hungarian attack, the Romanian army prepared to cross the Tisza River. The 7th Infantry Division returned from Bessarabia. The 2nd Infantry Division and some smaller infantry and artillery units also returned. The Romanian army massed 119 battalions , 99 artillery batteries with 392 guns and 60 cavalry squadrons . Hungarian forces continued an artillery bombardment. From 27-29 July the Romanian army tested the strength of the Hungarian defense with small attacks. A plan was made to cross the Tisza River near Fegyvernek, where it makes a turn. At the night of 29-30 July the Romanian army crossed the Tisza River. Decoy operations were mounted at other points along the river, bringing intense artillery duels. Romanian forces held the element of surprise. On 31 July the Hungarian army retreated towards Budapest.

Problem: The German government led by Adolf Hitler and the Nazi Party was responsible for the Holocaust , as well as for killing of 2.7 million ethnic Poles, and 4 million others who were deemed "unworthy of life" as part of a programme of deliberate extermination. Soviet POWs were kept in especially unbearable condition, and, although their extermination was not an official goal, 3.6 million of Soviet POWs out of 5.7 died in Nazi camps during the war. In addition to concentration camps, death camps were created in Nazi Germany to exterminate people at an industrial scale.Nazi Germany extensively used forced labourers. About 12 million Europeans from German occupied countries were used as slave work force in German agriculture and war economy. Soviet Gulag became de facto a system of deadly camps during 1942-43, when wartime privation and hunger caused numerous deaths of inmates, including foreign citizens of Poland and other countries occupied in 1939-40 by the USSR, as well as of the Axis POWs.By the end of the war, most Soviet POWs liberated from Nazi camps and many repatriated civilians were detained in special filtration camps where they were subjected to NKVD check, and significant part of them was sent to Gulag as real or perceived Nazi collaborators.
