What evidence does zinn provide to support his claims that the united states was motivated by other reasons(besides german attacks on u. s. ships)?

He motivated the US So that the United States can profit financially. England served as a market for American commodities and interest-bearing loans. America had put money into the Allies, and if they lost, they would lose it all.

Explanation:

During World War II, the United States had no authority to "come up as a defender of helpless countries." Zinn boils down the meaning of the world's largest war to its most basic elements:

from Dresden to Hiroshima. Zinn served as a bombardier in the European theatre during WWII and became a lifelong pacifist as a result of his service. However, it does not appear that Franklin Roosevelt and his associates were motivated by both realpolitik and a dislike of fascism.

The correct answer to this open question is the following.

Author Howard Zinn thinks that there were also economic reasons involved in the United States decision to participate in World War. Zinn provides the following evidence to support his claims that the United States was motivated by other reasons (besides German attacks on US ships).

He states that by 1914, the private foreign investments totalized $3.5 billion. Europe was a very good market to invest in for private investors such as J.P. Morgan. Many investors gave loans at interest to support the war effort. So there were many personal interests of American investors in an English victory over the Germans. That is why, the United States decided to enter World War 1 on April 6, 1917.

Howard Zinn wrote the book "A people's History of the United States," in 1980, where he referred about this issue.
