"During this period, Japan's peaceful commercial relations were successively obstructed, primarily by the American rupture of commercial relations, and this was a grave threat to the survival of Japan"

Hideki Tojo's quote is describing a period of time in which Japan's tranquil business relations were being impeded by the United States. This was a major issue for Japan, as it postured a severe danger to their survival. Tojo is implying that the United States was the main reason for this disruption, as they had broken off industrial relations with Japan. This had a substantial influence on Japan's economy, as it implied that they were not able to access the resources they required to make it through. The US's actions were seen as a direct danger to Japan's sovereignty and security, and it was a major factor in the nation's eventual downfall. Tojo's quote works as a tip of the power of the US and the disastrous effects of their actions.
