The Pearl Harbor bombing was important to World War II because it caused the most powerful industrial nation in the world to enter the war. For example we built more aircraft's in one year than the Germans could build in four years. We built ships faster than the German and Japanese could sink them.
As Stalin once said, "Quantity has a quality all its own." America had been against joining the war. Pearl Harbor ended all resistance against joining the war in one day. It changed a Navy attitude that the Battleship was the main naval weapon, that wars at sea would be settled by ships shooting it out with one another. Since most of our Battleships were sunk we were forced to use whatever we had and in that case it was the Aircraft Carrier. It didn't take long (Battles of Coral Sea and Midway) for the Carriers to prove the day of the Battleship was, for the most part,over. In those battle ships were sunk without ever seeing one another. The fighting between navies would no longer take place at distances of 20-30 miles, but in hundreds of miles. The USA was a well educated and well prepared industrial nation that was able to produce weapons
and fresh troops without having to constantly repair its own infrastructure. The British had been fighting the Germans for a number of years and were doing a good job of it. The USA had been supplying the British with a fantastic amount of weaponry even before they became involved in WW2. However with the Japanese being stupid enough to attack the US it caused Germany to declare war as well and it was on for young and old. The end result is that the US introduced fresh equipment and materials into the war and made absolutely sure that the debt incurred by Europe was repaid by her victorious Alys. The Japanese hierarchy were later rewarded by being made one of the wealthiest industrial nations in the world. And with only having to face perfunctory war crimes prosecutions. Pearl Harbor was the naval base that the United States Navy had a large portion of their naval ships and servicemen stationed. When Japan bombed Pearl Harbor, Hawaii on 12/7/41 on a Sunday morning the Japanese severely
crippled the ability for the naval force to wage war.
The Battle of Midway is important to World War II because it cripple the Japanese carrier fleet by sinking the Akagi, Soryu and the Kaga and damaging the Hiyu at the cost of the USS Yorktown. The Japanese invasion was aborted. Yes, Midway was a turning point. The Japanese lost
aircraft carriers that they could not replace. The US lost some ships, but not nearly as many as the other side. It was also an indication that the Japanese codes had been broken and much intelligence was available. The US actually lured
the Japanese to Midway and surprised them there. The importance of the Battle of Midway is that it can be considered as a major victory for the US as it removed 4 major carriers from the Japanese fleet and as
the battle itself had proved, these ships were vitally important in the age of aeroplanes winning naval battles rather than large destroyers and cruisers. The loss of Yorktown was a loss for the US but they had too,which means that they had to rebuild ships in quick time and the Japanese could not manage this. The Americans had gained control over the skies in the Pacific even though their planes were outclassed by the Japanese Zeros. However due to lack of Carriers the Zeros could not venture far from the mainland leaving the lesser planes in the USAAF with control of the skies. The main attack force of Cruisers and Destroyers in the Japanese fleet were forced to return to Japan and as a result their threat
vanished from the Pacific War.By removing the means to launch attacks, it could be said that The Battle Of Midway prevented the Japanese from getting on the front foot, and as a result they were forced into defense ahead of attack,
paving the way for victory for the Allied troops.
