Germany, Japan and Italy...............................
Japan. Also Germany and Italy, and a few smaller Axis countries.
There is only one Irish country: Ireland. It sided with Germany since it had strong tensions with the United Kingdom, not because it actually agreed with Nazism. (It was an "enemy of my enemy" thing.)
First Japan in the Pacific and then Germany .
Germany was a member of the Axis, and so an enemy of the Allies during World War 1 and World War 2. Today, Germany is the most powerful nation in Europe, a founding member of the European Union, and a strong ally of the US.

Germany was Britain's main enemy.
As of 2014, Germany does not have enemies, at least in the traditional sense of being enemies with Another Country. Al-Qaeda, the terrorist group, is considered an enemy of Germany. Germany is a member of NATO, the North Atlantic Treaty Organization.
WWII was basically Japan, Italy, and Germany versus every other country. (USA, Britain, etc.)
