Which belief decribes how most progressive felt in the early 20th century

Throughout the 20th century, Americans struggled to define the fundamental purpose of U.S. foreign policy: whether America should intervene abroad to promote the welfare of others or to secure the lives and liberty of American citizens. This struggle is one of the most enduring legacies of the Progressive revolution in American politics. Christopher Burkett contrasts the principles of Progressive foreign policy with those of the Founding and looks at three early examples of their application: the Spanish– American War and its aftermath, Theodore Roosevelt’s corollary to the Monroe Doctrine, and Woodrow Wilson’s decision to enter World War I in 1917. He shows how the Progressives’ idealistic foreign policy marked a profound departure from the Founders’ emphasis on prudence in the application of just principles.
