Should the Allies have fought to defeat Japan or Germany first?

answer:

>>Europe first, also known as Germany first, was the key element of the grand strategy agreed upon by the United States and the United Kingdom during World War II. According to this policy, the United States and the United Kingdom would use the preponderance of their resources to subdue Nazi Germany in Europe first.

>>In May 1940, the United States had made Pearl Harbor the main base for its Pacific Fleet. As Americans didn't expect the Japanese to attack first in Hawaii, some 4,000 miles away from the Japanese mainland, the base at Pearl Harbor was left relatively undefended, making it an easy target.
