The document provides the text of a speech given by Senator Henry Cabot Lodge in 1919 arguing against the United States joining the League of Nations. Lodge gives three main reasons: 1) America should focus on its own interests and problems rather than get tangled in European intrigues, which could destroy its power to do good; 2) Getting involved in Europe could endanger America's existence by drawing it into another European war; 3) America has its own grim and perilous problems to solve, and solving them could largely benefit mankind. The document then provides a question asking what reasons are given in the source for America's failure to join the League of Nations.
