In the Soviet Union until 1943. was great, heroic World War II, Poland was then West Germany (the capture of Berlin). Let us not forget that signed a nonaggression pact between Hitler and Stalin, which characterizes the USSR with the best hand (though they themselves for it and paid) and the creation of the United Nations, I think it would be good to take into account the fact that the Soviet Union is no better in Germany ( Well, if only the Jews were not killed, for thousands of his countrymen). Not counting the Great Patriotic War, the Soviet Union invaded Poland, a piece of West Germany including Berlin (due to its geographical location is not bad), and I almost forgot even the Czech Republic. I do not take into account the Baltic states because the Baltic states believe that they were not released and captured, argue with them will not, their cause. Although Poles, too, so many believe.
England, from the beginning of the war led the offensive against the Germans and Italians. North Africa (El Alamein and t.), And it should be noted that there was also a World War II (Egypt). If someone believes that there was a semblance of war, I sympathize with him and let him go just honors more books. Then from the British was France, the Netherlands, could be attributed to another Belgium and Germany, but it's the merits of other countries. But still significant contribution to the war.
US until 1942 very well to improve the economy and food supply weapons to the USSR. 1941 began active operations against Japan, Italy, captured in 1944, liberated France, Holland, Belgium (Siegfried Line), eastern Germany. Japan surrendered due to the pressure of the United States. It should be noted that the first Americans sent troops to Germany on the eve of the capture of Berlin, President Roosevelt died, was replaced by the gene. D. Eisenhower who loved his army and not let them die in Berlin, but left this occupation Russian.
