Who were Britan fighting against in World War 2?

The Britons fought against the axis powers in both the Pacific Theater of Operations and the European Theater of Operations. This means they fought against the big 3 axis powers of Japan, Germany and Italy. There were smaller nations they had to battle as well, such as African nations and the French Vichy. They "owned" many other nations and islands as an imperialist nation which Japan and Germany attacked or took over. Conflicts between the Brits and Turkey, Iraq, Iran, Egypt and other Arabian nations did exist during World War 2. Some of these conflicts and issue resulted in the 1948 war in Israel.

The primary enemy however was Adolf Hitler and the Nazi Germans. They poured the bulk of their money, supplies, war equipment and men into their effort to defeat and destroy Nazism. The Allied Forces all put the most effort into the European War. The Pacific Theater took a back seat but they did defeat the Japanese with the thinner budget and allotment of men and equipment.
