The United States spent the first years of World War II keeping its military out of the conflict. Though it lent aid to the British, it refused to outright join and declare war on any of the Axis powers. From 1939 to 1941, the nation was able to maintain its isolationism. Then came December 7, 1941, a dark day in American history. What was America’s response to Pearl Harbor?
Response to Pearl Harbor
Battleship Row, Pearl Harbor December 7, 1941
In the quiet of a tropical Sunday morning, a Japanese aerial striking force flew over the island of Oahu, part of the American Territory of Hawaii, and launched a surprise assault on multiple military installations. Airfields were devastated, their aircraft destroyed to prevent a counter-strike, but the majority of the damage was centered around Pearl Harbor, the naval base on the southern part of the island.
Eight battleships of the US Pacific Fleet were present at Pearl Harbor that morning, and it was Japan’s intention to destroy each of them. The purpose? To keep the Americans from meddling in the conflict taking place more than 3,000 miles across the Pacific. The attack on Pearl Harbor left more than 2,400 Americans dead and shocked the nation, sending shockwaves of fear and anger from the West Coast to the East.
The following day, President Franklin D. Roosevelt addressed Congress, asking them to declare war on Japan, which they did by an almost-unanimous vote. But perhaps surprisingly, the nation’s first response to Pearl Harbor wasn’t made in the Pacific.
Explanation:
That move was made across the Atlantic, in the European Theater. The reason for this was that in response to the American declaration of war on Japan, Germany and Italy declared war on the United States. The shock of the Japanese attack was still fresh in the minds of the American public when Congress was forced to reply to the German and Italian declarations by also declaring war on them.
With a war on two fronts, Congress and Roosevelt were forced to decide what the first move would be. How would the United States, a nation that never wanted to join World War II, deal with both the Pacific and European fronts? Would it be a matter of dealing with both the Japanese and the Germans at the same time? Would one need to be the focus before the other could be made a priority?

While the nation may have assumed Japan was going to be the priority, there were two major differences between the Pacific and European theaters. Adolph Hitler’s forces had captured considerable territory in Europe, which posed a greater immediate threat to the world than Japan’s conquest of Asian territories. With much of Europe and the Atlantic under Nazi control, the United States was at risk of being the next target.
Compared to Japan, Germany was also far more militarily advanced. German scientists and engineers worked tirelessly to develop dangerous weapons of war and one of Roosevelt’s prime concerns was the nation’s creation of unmatched weaponry. An atomic bomb was a very real concern that would have proven devastating to the world if placed in Hitler’s hands.
If those concerns weren’t enough, the United States had been urged by the United Kingdom to join the war against the Axis from the beginning the conflict. Even if the US had intended to assist the Chinese first, the British were considered better equipped to put up a fight against Germany. Across the Pacific, China’s military was considerably weaker than Japan’s and wouldn’t be able to lend much help in the war in the Pacific. For the most part, it would land on the US Navy to take on the Japanese in the Pacific. Prime Minister Winston Churchill worked closely with Roosevelt on a “Germany First” war strategy, hoping to prevent the United States from having to divide resources between Europe and the Pacific.
Though it would seem to make sense to try and strike Japan early on, and prevent them from taking territories across the Pacific, Hitler, and the urging from Churchill, made Roosevelt’s decision easier. By attacking the Soviet Union, Germany’s forces were suddenly fighting a war on two fronts. With their focus divided between east and west, it made strategic sense to try and knock Germany out of the war first. Hope this helps!
