Question

Which of the following is the best support for German's claim that the United States has "abundant cause for war"?

Answer 1

I had to look for the options and here is my answer:

The phrase ""abundant cause for war" refers to the war between Great Britain and France against the United States which occurred in the year 1812. The one that states about the German's claim that the US has "abundant cause for war" is the controversy over the Louisiana Purchase.
