Final answer:
Territorial aggression is not necessary for a great economy and Japan's economic growth can be attributed to other factors such as industrialization, investment in the economy, and favorable trade agreements.
Step-by-step explanation:
The question of whether territorial aggression is necessary for a great economy is complex and does not have a simple answer. While it is true that Japan engaged in territorial aggression before and during WWII, it is not accurate to say that this aggression was necessary for Japan to have a great economy. The rapid economic growth that Japan experienced in the post-war period can be attributed to a combination of factors such as industrialization, investment in the economy, and favorable trade agreements.
As explained in the references, Japan already had an industrialized society before the war and the United States provided aid and investment after the war to help Japan rebuild its infrastructure. Additionally, Japan focused on low-wage industries and exported products to the United States. These factors, along with Japan's own efforts in rebuilding and investing in the economy, contributed to its economic growth and development.
It is important to note that territorial aggression is not a prerequisite for a great economy. There are many other examples of countries that have achieved economic success without engaging in territorial aggression.
