Explanation:

Prior to World War I, the United States had a policy of neutrality and isolationism. Forming international military alliances (a key cause of the war's escalation in Europe) was against this stance. Creating military bases in strategic sea - ports was not a major pre - WWI diplomatic focus. Expanding transatlantic trade was important but not the most concerning diplomatic issue compared to the geopolitical implications of alliances.

None of the above
