Explain what effect the embargo of gasoline, machine tools, scrap iron and steel had on Japan. (Think about what those items can be used for, and what happens if they can no longer be imported from other countries.)

The embargo of gasoline, machine tools, scrap iron and steel had a significant negative impact on Japan. These items are essential for the country's industrial production and military capabilities.

Gasoline is crucial for powering vehicles and machinery, as well as for transportation purposes. Without access to gasoline, Japan's economy would grind to a halt, as transportation and manufacturing industries would be severely crippled.

Machine tools are crucial for the manufacturing process, as they are used to produce other goods and equipment. Without access to machine tools, Japan's ability to produce goods and equipment would be severely limited.

Scrap iron and steel are essential for the construction of buildings, infrastructure, and military equipment. Without access to these materials, Japan would struggle to maintain or expand its industrial and military capabilities.

Overall, the embargo of these essential materials severely hampered Japan's ability to function as a modern industrialized nation and posed a significant threat to its military readiness.
