EXPLANATIONS BELOW
Concept note-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.
Concept note-2: -President Roosevelt swung into action by freezing all Japanese assets in America. Britain and the Dutch East Indies followed suit. The result: Japan lost access to three-fourths of its overseas trade and 88 percent of its imported oil.
Concept note-3: -The United States placed an embargo on scrap-metal shipments to Japan and closed the Panama Canal to Japanese shipping. That hit Japan’s economy particularly hard because 74.1% of Japan’s scrap iron came from the United States in 1938, and 93% of Japan’s copper in 1939 came from the United States.
Concept note-4: -Roosevelt hoped that such sanctions would goad the Japanese into making a rash mistake by launching a war against the United States, which would bring in Germany because Japan and Germany were allied.
Concept note-5: -When Japan occupied French Indochina in 1941, America retaliated by freezing all Japanese assets in the states, preventing Japan from purchasing oil. Having lost 94% of its oil supply and unwilling to submit to U.S demands, Japan planned to take the oil needed by force.
