Franklin D. Roosevelt (1882 - 1945). 32nd U.S. President

On the other side of the Atlantic, one of the major players in WWII just woke under the leadership of its 32nd President Franklin D. Roosevelt (1882 - 1945). Long hesitant to formally take part in the European Theater though logistically supporting Britain, the U.S. had no choice. The Japanese attack on Pearl Harbor made their involvement inevitable, as declaring war on Japan on Dec 8, 1941 led Germany and Italy to declare war on the U.S. on Dec 11. The U.S. responded with a declaration of war on both immediately. Canada and Australia declared war on Japan a few hours before the U.S. did. (as the attack on Hong Kong and the Malaya on the same day was also an attack on the British Empire.)

Here's my colorized take of a photo of FDR ca, 1933, his first year as President that would extend to 4 terms of office with the last two engaged in the war effort on two fronts - Europe and Asia. The involvement of the US and Japan gave the war that started in Europe its global reach between 1941 and 1945.
