It is not denied that the entry of the United States in World War II accelerated the defeat of the Fascist Axis Alliance and made an important contribution to the ushering in world peace. If the United States still maintains the political scale of "isolated diplomacy" of "only sweeping the snow before the door" before the war, rather than having a strong ambition to dominate the world after winning the final victory in the war, it can be said that the important role played by the United States will certainly be respected by all countries in the world.
Unfortunately, after the victory of the United States in World War II, the strong comprehensive national strength that made him breed a sense of super superiority and the arrogance of the world in his heart began to be oblivious in the international community, which was inseparable from the Western political ideology, social system and the natural perspective of communist ideology hostile to the socialist camp. Therefore, in 1946, the second year after the end of World War II, the close alliance formed by the United States, the Soviet Union, and Britain was replaced by the Cold War Iron Curtain in a short period of time, and the world pattern emerged with the United States and the Soviet Union as representatives of the opposing east and west.
In June 1950, the Korean Civil War broke out, the United States directly sent troops to interfere in the internal affairs of Korea, which eventually led to China launching the War to Resist US Aggression and Aid Korea in order to defend the security of national sovereignty, which crushed the United States' attempt to occupy the Korean Peninsula and also taught the United States the strength of the New China Army.
In the Pacific Theater of World War II, the U.S. army destroyed the Japanese army and pushed straight into the Japanese mainland.
With the outbreak of World War II, the West set the german invasion of Poland in 1939 as the starting point of the war. At that time in Asia, the Japanese army had been launching a war of aggression in China for 8 years. The 9.18 Incident of 1931 invaded and occupied all of China's three eastern provinces, and six years later, on July 7, 1937, on July 7, 1937, they launched a full-scale war of aggression against China at Lugou Bridge in Beiping (today's Beijing), known in history as the "Lugou Bridge Incident", also known as the "July 7 Incident", and the Sino-Japanese War broke out in full swing. Strictly speaking, the real starting point of World War II should be China in Asia.
With regard to the Japanese war of aggression against China that broke out on the Chinese mainland, the Western world at that time continued its historical dismissive attitude toward China, believing that this ancient Eastern country was not worth helping at all, because it was a declining country with foreign powers, and if it did not involve its own interests in China, there was no need to lend a helping hand to offend Japan. The war lasted until the Japanese attack on Pearl Harbor on December 7, 1941, and the assistance of the United States and Britain to Japan's military resources remained actively supplied, and it was the appeasement policy of the United States and Britain that made the Japanese army unscrupulous in launching the war of aggression against China. When the United States declared war on Germany and Japan, China's all-out war had been fought for four years. After making great sacrifices, the Japanese invading army was trapped in the quagmire of the Chinese battlefield and could not extricate itself, and the resolute resistance on the Chinese battlefield pinned down more than 2.5 million regular troops of the Japanese army, which made an important contribution that could not be underestimated for the final victory of the United States in the Pacific theater and even the entire world anti-fascist battlefield.
Japan's sneak attack on Pearl Harbor, purely from a military point of view, can be called the most perfect sneak attack, this military operation that concealed the sky and crossed the sea, gave the US Pacific Fleet a heavy blow, in addition to the temporary aircraft carriers, all the battleships, cruisers and destroyers in the harbor were almost sunk, including more than 260 combat aircraft at the airport, and the US Pacific Fleet was completely lost. For more than half a year, the U.S. Pacific Fleet never saw the shadow of the U.S. Pacific Fleet on the surface of the southwest Pacific Ocean. The Japanese army seized the opportunity to capture the Philippines, Singapore, Malaysia, Indonesia and other Southeast Asian oil, rubber and other resource-rich countries. General MacArthur, the supreme commander of the Southwest Pacific stationed in the Philippines at the time, withdrew from the Philippines at night by a torpedo boat, and lost more than 70,000 American troops under his command to the Japanese, and finally these American troops surrendered to the Japanese. This was seen as a great shame by MacArthur and vowed to return.
In June 1942, the U.S. Pacific Fleet, supported by a strong U.S. industrial system, quickly recovered. In midway with the Japanese combined fleet, the sinking of four Japanese heavy aircraft carriers achieved the most important naval victory since the outbreak of the Pacific War, which is also known as the turning point of the Pacific Theater, and it was after this naval battle that the Japanese Combined Fleet changed from a southward attack to a defensive combat posture. From this moment on, the US military began to gradually move toward the stage of counter-offensive operations. Two months later, the U.S. military launched an attack on Guadalcanal Island (guadalcanal), an important maritime base of the Japanese army, which lasted for half a year, with more than 5,000 U.S. casualties and more than 110 fighters, while the Japanese army killed more than 24,000 people, lost more than 800 aircraft, and lost more than 2,000 pilots. In February 1943, the Japanese army secretly withdrew from Guadalcanal, and the American army occupied this important base, gaining an absolute strategic advantage. The battle also made The Pacific Fleet Commanders Nimitz and MacArthur sober up about how terrible the Japanese soldiers were under the influence of crazy militarism.
In order to better prepare for the war, the Allied forces and the Japanese army after the Battle of Guadalcanal entered a brief confrontation in the Pacific Theater, which lasted until June 1943, when the Strategic Counteroffensive launched by the American Army began. During this period in April, the commander of the Japanese Combined Fleet, Isoroku Yamamoto, who planned the attack on Pearl Harbor, was shot down by American aircraft and killed. By the end of the year, the US military had successively captured the islands of Marshall, Bougainville and other islands, and the aviation bombing radius was extending to the Japanese mainland step by step. The Burma Campaign in which China participated was fought in Burma in November, in which more than 100,000 people of the three armies of the Japanese army were annihilated by the Allies by more than 73,000 people, and there was no longer the ability to counterattack. Since 1944, whether at sea or in the jungle on land, the Allied counter-offensive has formed a super combat force, and the Japanese army has no other way to retreat on the battlefield except surrender, die in battle, or commit suicide by caesarean section. On October 20 of that year, MacArthur stepped down from the landing ship and waded through the sea to make an important speech on his return to Philippine soil, the most famous of which was: I am back. This was the moment when he most proudly struck out his promise.
After the Battle of the Philippines and the Battle of Leyte Gulf, the Japanese naval power has basically ceased to exist, and the Allied forces suffered the largest casualties in the Japanese island capture operations on Iwo Jima and Okinawa, especially in the Okinawa Island Capture Battle, the American casualties were more than 75,000, which was the most sacrificed in the Pacific Island Capture Operation. The Japanese suffered more than 110,000 casualties, not counting 100,000 Japanese civilians, with a total casualty of more than 200,000. After the occupation of Okinawa, the Allied B-29s could directly bombard the Japanese mainland, and the time of Japan's demise entered the countdown. U.S. President Harry S. Truman was shocked to hear that the capture of the Japanese mainland could cost the U.S. military millions of soldiers. In the end, it was decided to use the two atomic bombs just developed by the United States to urge Japan to surrender with a nuclear force strike. A week after two mushroom clouds rose in Hiroshima and Nagasaki, Japan, the Emperor of Japan finally announced the armistice on the radio, and by this time the tens of millions of armed forces that had been mobilized on the Japanese mainland were almost all old people and children. The US military's counter-offensive operations in the Pacific for more than two years have been fought by the Japanese army all the way to no respite, and every battle will be lost, with countless casualties. After the war, the defeated Japanese army saw the Americans on the mainland like slaves, including their emperor, who was always cramped like a child who had done something wrong in front of MacArthur, the commander of the occupying forces. To this day, Japan's subservience in front of the Americans is the result of being hanged by the Americans all the way in the Pacific.
American troops entered the European theater, and Hitler's Germanic lightning division was crippled.
The day after Japan's attack on Pearl Harbor, the United States declared war on Japan, and Hitler officially declared war on the United States on December 11, two days after the United States declared war on Japan. Roosevelt finally got a reason to go straight to war, and roosevelt tried many ways to get such an opportunity, but they were all snuffed out by the widespread war-weariness in the United States. Because the American people are very satisfied with the beautiful living environment in front of them, and the wars in Asia and Europe are related to their United States. When the Germans occupied France, the far-sighted Roosevelt had a premonition that the days when the United States would be alone were running out, but American public opinion did not show concern about this, but gave more numbness and indifference to the Eurasian battlefield far away from the United States. The United States could only provide military aid and loans in the form of the Lend-Lease Act to countries such as Britain, the Soviet Union, and China that were fighting Germany, but this did not weaken the military offensive launched by Germany and Japan. The huge war machine of the United States could only watch as the increasingly severe situation approached itself, and it was not until after the Japanese attack on Pearl Harbor that the American people discovered that the war was so close to them.
When British Prime Minister Winston Churchill learned that the U.S. Pacific Fleet had been wiped out by Japan, he shouted excitedly: We have won! Stalin raised an eyebrow and said to the people around him: "Do these yellow-faced monkeys in Japan know what they have done?" Hitler learned that the Japanese had launched a sneak attack on the United States in secret, and his expression was very complicated, and when his submarine "Wolf Pack" inflicted heavy damage on the British transport fleet in the Atlantic, he did not forget to warn his submarine commander Dönitz: Avoid attacking any ship flying the American Star-Spangled Banner. But now that Japan has dragged the United States into the war, Hitler is worried about the situation in the future war. But from a coalition perspective, he had to declare war on the United States.
With the strong national comprehensive strength of the United States, the military force is very frightening once deployed. In a short period of time, the war mobilization recruited nearly 6 million armed forces to the European and Asian Pacific theaters, and the complete military industrial system was fully launched overnight, and aircraft, warships, tanks, artillery, firearms, ammunition and other military products began to be continuously released on battlefields around the world. Roosevelt's first consideration was Europe, where there were not only traditional political allies of the United States, but also because Europe was the richest region in the world, and if it was completely occupied by Germany, the future United States would face the whole of Europe. As long as there are enough combat ships and aircraft carriers in the wide Pacific Ocean, Japan can only temporarily dominate Southeast Asia, and japan's combat capability cannot be reached to reach the Western Hainan of the United States. He dropped nearly 80 percent of the U.S. Army's 62 divisions into Europe, while maintaining only 27 infantry divisions in the Pacific Theater, six of which were Marine divisions. The fate of the Axis powers was doomed from this moment on.
From July to November 1942, the Soviet Union won the victory in the defense of Stalingrad and began to launch counterattack operations; in October, the British army launched the Battle of El Alamein in Africa, defeating the German desert fox Rommel; the United States and Britain allies landed in North Africa in November, launching the "Torch Plan" aimed at attacking the Axis Italy, capturing Algiers, Oran and Casablanca successively. In March 1943, the United States and Britain allies invaded Tunisia again, and the Italian army fled in disguise; in July, the American army and the British army landed in Sicily and launched an attack on Italy, a campaign personally commanded by Eisenhower, the Axis captives alone captured 140,000 people, most of them Italian soldiers, Mussolini was also controlled by Italian coup officers, and later rescued by Hitler. After the capture of Sicily, the Allies had fully formed a favorable situation for the Italian offensive.
In all the operations of 1943, the U.S. offensive was not all smooth, and the North African landings, raids on Tunisia, and the capture of Sicily were victorious, but the price paid was extremely heavy. By 1944, with the maturity of combat experience and the increasing strength of military equipment, the situation of the Collapse of the Axis Powers was irreversible. By June, the Allies had launched the most important and valuable battle on the European front since the beginning of the war, the landings in Normandy, France. In this landing operation to open up the second european battlefield to alleviate the pressure of the Soviet Union's frontal military operations, the Allies gathered more than 2.6 million troops and landed from Normandy, France, swept away the whole of France, and inserted the Allied sharp front directly into the German mainland.
In order to save the situation, Hitler continued to struggle to gather 200,000 German troops in December to launch the Ardennes counterattack, which caused great passivity to the Allies at the beginning of the battle, but was soon controlled by the Allies, gathering 700,000 heavy troops to launch a counter-offensive operation and annihilating more than 100,000 German troops. After the Battle of the Ardennes, the Germans had no counter-offensive forces and were defeated all the way. In March 1945, the Allies organized the Battle of the Ruhr in Germany, annihilated the German Army Group B, captured more than 320,000 German prisoners of war, and met the Soviet army on the Elbe, and Hitler's end was just around the corner. On April 16, 1945, Soviet Marshal Zhukov commanded 2.5 million Soviet troops to launch a final attack on the German capital Berlin, Hitler committed suicide in the bunker, and Germany announced its surrender.
In world war II, the United States became the biggest winner of all the participating countries, not only controlling the world's highest voice, but also forming a more powerful military force in the United States on the ruins of the old capitalist countries such as Britain and France, which were in decline, including the vast Soviet Union, and there was no doubt that it was inferior to the United States. The ambition of the U.S. government began to generate a strong desire to dominate the world, and this hegemonic ideology has not been reined in to this day.
