In the last century, the most far-reaching and costly war was the Second World War, in which the Allies fought against the Fascist Axis, paid countless sacrifices, and finally completely defeated the fascist aggressors.
In World War II, there were many turning points, in the European battlefield, the Soviet Union's several city defense battles, the German army unstoppable attack blocked, and gradually began to counterattack, normandy landing is set off the prelude to the Allied counteroffensive, and in China's anti-Japanese battlefield, a Songhu Battle of The War of Resistance against Japan evolved into a full-scale war, Japan can no longer achieve the dream of "three months to destroy China", the Battle of Wuhan, our army is brave, killing and injuring 257,000 Japanese troops, the War of Resistance Against Japan into a stalemate stage.
But the turning point of the whole World War II was not these wars, but a great victory for the fascist countries, that is, the successful japanese attack on Pearl Harbor, on December 7, 1941, the Japanese Navy sent a large army to successfully attack the U.S. Navy's Pacific Fleet ships in Pearl Harbor in the early morning, and the U.S. Army and Navy airfield on Oahu, when the U.S. Navy had 8 battleships, 3 cruisers, 3 seaplane supply ships, and 29 destroyers berthed in Pearl Harbor.
Due to the japanese attack without warning, the unprepared U.S. Navy suffered heavy losses, 4 battleships were sunk, 1 stranded, 3 were severely damaged, 9 cruiser destroyers were damaged, thousands of officers and men were killed and wounded, the Pacific Fleet except for aircraft carriers, almost completely destroyed, while the Japanese army only lost 29 aircraft and 55 pilots, tactically speaking, the Japanese army won a big victory.
However, after the victory of this operation, when the Japanese army cheered, Japanese Admiral Yamamoto Fifty-six painfully warned the Japanese army that was reveling, in fact, this did not mean victory, the Japanese army just let an enemy they could not defeat wake up, and it was true, the attack on Pearl Harbor made the United States angry, and then quickly decided to participate in the Second World War, the United States, the world's first industrial power at that time into the Camp of the Allies, the unparalleled war machine running at full speed, The situation in World War II gradually became clear.
In the middle of World War II, although the United States relied on the Lend-Lease Act to give a lot of material support to various countries, it never really participated in the war, and Japan's sneak attack on Pearl Harbor completely angered the United States, and the United States set off an anti-fascist upsurge throughout the country, countless teenagers took the initiative to enlist in the army, the whole country entered a state of war, and almost all factories began to produce war materials.
The United States entered the Pacific Theater and the European Theater, with the help of this behemoth, the Allies gradually grasped the initiative of the war, although even if the United States did not join, the Allies still have the ability to win, but the loss will be more, but the participation of the United States, so that the situation in World War II is really clear, so it is said that the Japanese attack on Pearl Harbor is the turning point with the greatest impact on World War II.
