On December seven, 1941, Japan staged a surprise assail on Pearl Harbor, decimating the US Pacific Fleet. When Germany and Italia declared state of war on the United States days later, America establish itself in a global war.

The Roots of the Conflict

While Nippon's deadly assault on Pearl Harbor stunned Americans, its roots stretched back more than than four decades. As Japan industrialized during the late 19th century, information technology sought to imitate Western countries such as the Usa, which had established colonies in Asia and the Pacific to secure natural resource and markets for their goods. Nippon's process of regal expansion, however, put it on a collision course with the U.s., particularly in relation to China.

To a certain extent, the conflict between the United States and Nippon stemmed from their competing interests in Chinese markets and Asian natural resource. While the The states and Japan jockeyed peaceably for influence in east asia for many years, the situation changed in 1931. That year Japan took its showtime pace toward building a Japanese empire in eastern asia past invading Manchuria, a fertile, resource-rich province in northern China. Japan installed a puppet authorities in Manchuria, renaming it Manchukuo. But the The states refused to recognize the new authorities or any other forced upon China under the Stimson Doctrine, named after Secretarial assistant of Land and future Secretary of State of war Henry L. Stimson.

The ineffectual Stimson Doctrine guided Us policy in Asia for the next decade. On the i manus, the doctrine took a principled stand in support of Chinese sovereignty and against an increasingly militaristic Japanese regime. On the other paw, withal, it failed to bolster that stand with either material consequences for Japan or meaningful support for China. In fact, US companies continued to supply Nihon with the steel and petroleum it needed for its fight against China long after the conflict betwixt the countries escalated into a full-scale war in 1937. But a powerful isolationist movement in the United States countered that the nation had no business at all in the international conflicts developing around the globe. Even the Japanese military machine'due south murder of betwixt 100,000 and 200,000 helpless Chinese military prisoners and civilians and the rape of tens of thousands of Chinese women during the 1937 Rape of Nanking failed to immediately shift U.s.a. policy.

The strong isolationist movement also influenced the initial The states approach to the war in Europe, where by the end of 1940 Nazi Germany controlled most of French republic, Central Europe, Scandinavia, and North Africa, and severely threatened Great Uk. Prioritizing the war in Europe over Japan's invasion of People's republic of china, the U.s. immune the sale of military machine supplies to Great United kingdom of great britain and northern ireland commencement in 1939. Only neutrality laws and isolationist sentiment severely express the extent of that aid prior to 1941.

"Each [nation] stepped through a series of escalating moves that provoked but failed to restrain the other, all the while lifting the level of confrontation to e'er-riskier heights."

David 1000. Kennedy, PhD

The state of war in Europe had another significant impact on the war in the Pacific considering Federal republic of germany's armed forces successes unsettled the other European nations' Asian colonies. As Japan seized the opportunity to become the dominant regal power in Asia, Usa-Japan relations soured. As historian David M. Kennedy, PhD, explained, "Each [nation] stepped through a serial of escalating moves that provoked merely failed to restrain the other, all the while lifting the level of confrontation to always-riskier heights."

The Impending Crisis

President Franklin Delano Roosevelt made one of those escalating moves in July 1940 when he cut off shipments of scrap iron, steel, and aviation fuel to Japan even as he immune American oil to continue flowing to the empire. Japan responded by entering resource-rich French Indochina, with permission from the government of Nazi-occupied French republic, and by cementing its brotherhood with Deutschland and Italy every bit a member of the Axis. In July 1941, Japan then moved into southern Indochina in preparation for an set on against both British Malaya, a source for rice, rubber, and tin, and the oil-rich Dutch East Indies. This prompted Roosevelt to freeze all Japanese assets in the U.s.a. on July 26, 1941, which effectively cut off Japan's access to US oil.

That move pushed Japan to secretly ready its "Southern Functioning," a massive military attack that would target Corking Britain's big naval facility in Singapore and American installations in the Philippines and at Pearl Harbor, thus clearing a path for the conquest of the Dutch East Indies. While diplomatic talks continued between the United States and Japan, neither side budged. Japan refused to cede any of its newly acquired territory, and the United States insisted that Nihon immediately withdraw its troops from China and Indochina.

The Assail

On November 26, 1941, as U.s. officials presented the Japanese with a 10-indicate statement reiterating their long-continuing position, the Japanese Imperial Navy ordered an fleet that included 414 planes aboard vi aircraft carriers to set to sea. Post-obit a plan devised by Admiral Yamamoto Isoroku, who had before studied at Harvard and served as Japan'south naval attaché in Washington, DC, the flotilla aimed to destroy the US Pacific Fleet base of operations at Pearl Harbor.

To grab the Americans by surprise, the ships maintained strict radio silence throughout their 3,500- mile trek from Hitokappu Bay to a predetermined launch sector 230 miles north of the Hawaiian island of Oahu. At 6:00 a.thousand. on Sun, December 7, a first wave of Japanese planes lifted off from the carriers, followed by a second wave an hour later. Led past Captain Mitsuo Fuchida, the pilots spotted land and assumed their attack positions around vii:xxx a.k. Twenty-iii minutes after, with his bomber perched above the unsuspecting American ships moored in pairs along Pearl Harbor'south "Battleship Row," Fuchida broke radio silence to shout, "Tora! Tora! Tora!" (Tiger! Tiger! Tiger!)—the coded message informing the Japanese fleet that they had caught the Americans by surprise.

For well-nigh two hours, Japanese firepower rained downwardly upon American ships and servicemen. While the attack inflicted meaning devastation, the fact that Japan failed to destroy American repair shops and fuel-oil tanks mitigated the damage. Fifty-fifty more than significantly, no American shipping carriers were at Pearl Harbor that day. The Japanese, however, immediately followed their Pearl Harbor assault with attacks against US and British bases in the Philippines, Guam, Midway Isle, Wake Island, Malaya, and Hong Kong. Within days, the Japanese were masters of the Pacific.

In Washington, a decrypted message had alerted officials that an attack was imminent moments earlier Fuchida's planes took to the skies. But a communications delay prevented a alarm from reaching Pearl Harbor in time. The Americans missed another opportunity when an officeholder discounted a written report from an Oahu-based radar operator that a large number of planes were headed their way.
