JOHN C. HULSMAN writes for ORF: There was no longer any way to put it off; in July 1940, the army-dominated government of Imperial Japan had come to a strategic fork in the road. Angered by its ongoing aggression in China, the western powers (the US, UK, and the Netherlands) had enacted a full oil embargo to stop Tokyo’s militarism in its tracks. Despite its stockpiles, the Japanese high command knew this was a potentially game-changing economic blow as, together, the three countries supplied Tokyo with an overwhelming 90 percent of its energy needs. Unless Japan engaged in the most humiliating about face, ending its adventurism in China (on which its government had staked everything), Tokyo’s economy would soon literally grind to a halt. A decisive strategic choice had to be made, and quickly.
