Name the Axis powers and their leaders and the Allied powers and their leaders during World War II.

While there
were many countries involved inon both sides, only a few of them were really relevant to the
course of the war as a whole.  I will list the major countries for each side and their
leaders.

On the Axis side, there were three major countries at the beginning
of the war.  These were Japan, Germany, and Italy.  Germany and Italy were fascist
dictatorships.  Their leaders were Adolf Hitler and Benito Mussolini, respectively.  Japan's
leader is harder to identify.  The head of state was the Emperor Hirohito.  However, he was more
of a figurehead than the other leaders mentioned here.  Hideki Tojo was the Prime Minister and
head of government for most of WWII.  If Japan could be said to have had a single leader, it
would have been Tojo.

On the Allied side, there were also three main
countries as of December 8, 1941.  By that point, France was no longer a major force on the
Allied side.  The main Allied powers were the Soviet Union, led by Josef Stalin, the United
Kingdom, led by Winston Churchill, and the United States, led by Franklin D.
Roosevelt.
