All of Eastern Europe.
The USSR
The Soviet Union
Through 1944 that would be Germany, after that Russia controlled and held eastern Europe for decades.
Not sure but if I had a guess it probably was the soviet union (russia)
Japan, Yes but not Easter Europe. Eastern Europe was controlled by the communist USSR. The USA only held up to West Berlin.
Because the Soviet Union controlled Eastern Europe for four decades. This changed when they elected a new leader, Mikhail Horbachev, he gave Eastern Europe more freedom as one of his reforms.
All of them. The Soviet Union occupied everything from the Russian border to the middle of Germany, and then formed some "puppet" governments to nominally "rule" the nations of eastern Europe, but everything was still controlled from Moscow.
The largest populated country in Eastern Europe is Russia.
Russia is the largest country in eastern Europe. It is also the largest country in the world.
Western Europe became industrialized much earlier than Eastern Europe and the entire world, which is why Western Europe has the largest economy in the world.
