The correct answer to this open question is the following.
Although there are no options attached we can say the following.
According to journalist Henry Luce, publisher of Time magazine. the United States had enough power to become the "savior" of the world and have a tremendous presence in the 20th century in foreign relations.
Luce did not agree with the idea of the United States maintaining the foreign policy of neutrality being isolated from the world's problems.
Henry Luce -who coined the term "American Century," the United States were ready to be a protagonist of the world history and demanded the US entered World War II. The reason, to help prevent the advancement of the Germans who could risk the western democracy and risk people's liberties.
For Luce, the 20th century should be a consolidation of the power and international presence for the United States. The problem was that Luce never considered the opinion of the other countries of the world that have always opposed the US interventionist plans.
