USA HISTORY

Detailed explanation-1: -The United States responded to this growing threat by temporarily halting negotiations with Japanese diplomats, instituting a full embargo on exports to Japan, freezing Japanese assets in U.S. banks, and sending supplies into China along the Burma Road.

Detailed explanation-2: -Japan’s immediate response was to occupy Saigon, again with Vichy France’s acquiescence. If Japan could gain control of Southeast Asia, including Malaya, it could also control the region’s rubber and tin production-a serious blow to the West, which imported such materials from the East.

Detailed explanation-3: -On September 27, 1940, Japan signed the Tripartite Pact with Germany and Italy, thus entering the military alliance known as the “Axis.” Seeking to curb Japanese aggression and force a withdrawal of Japanese forces from Manchuria and China, the United States imposed economic sanctions on Japan.

Detailed explanation-4: -Rather than send troops, US and European leaders called for economic sanctions and warned that harsher steps would follow if Japan continued its aggression. President Roosevelt banned the exports of some armaments and aircraft parts to Japan in 1940 after its leaders formed a military alliance with Germany and Italy.

Detailed explanation-5: -Within an hour of Roosevelt’s speech, Congress declared war on the Empire of Japan amid outrage at the attack, the deaths of thousands of Americans, and Japan’s deception of the United States by engaging in diplomatic talks with the country during the entire event.
