World War II--A Brief History
Though many now believe that the 1914-1918 War could perhaps have been avoided, there were entirely unavoidable reasons for the 1939-1945 War. It was a crusade against the evil and totalitarian regimes which then existed in Germany, Italy and Japan. It was waged by the Allied nations as a struggle for freedom. It was a necessary war, which simply had to be fought to the finish.
