Some Americans, called internationalists, were powerfully in approval of full contribution in world businesses. Other Americans, disgusted at the toll of World War I, turned private.

I believe the answer is <span>the Treaty of San Lorenzo, or Pinckney's Treaty</span>
Imperialism was one of the causes of World War 1. Imperialism means that two countries want to invade the same piece of land as one another. This will result in war because both countries will fight for who gets to take over the other country.
Economic competition was another cause because it was a rivalry of which countries had more profits.
