Answer:
The toll addiction takes on a person’s life — family, friends, career, emotional and physical health, finances and personal safety — is staggering. Right now, more than 21 million Americans have some sort of substance abuse disorder. Despite the crushing effects addiction can have, only one person in every five of those suffering receives the help they need.
militarism: Commiting to military
alliances: Friends of countries that help in wartime
imperialism: Desire to colonize, for glory, riches, or global domination
nationalism: Believing in your country's greatness
Japanese Imperialism led to colonizing parts of china, since it was mad at western powers colonizing china and pushing it out (hypocrisy). Italy was a rising economy, but bitter of not getting a fair share of land. German nationalism was at a high as the emerging Nazi (nationalist socialist) party was overturning the inflation ridding weimar republic. The failing alliance of the League of nations was falling apart quickly. Soon Japan, Italy, and germany turned to Imperialism, Fascism, Nationalism, and militarism and the world would find itself in another world war.
When it came to the Congress to approve the joining of the United States in the League of Nations it was blocked by the Republican opposition, especially from Senators William Borah and Henry Cabot (D).
The U. S. public opinion was still disappointed over the outcomes of the war. Also, the Republican Senators did not like what they thought to be a violation of the U.S. sovereignity: the covenant of the League in it's Article X predicted that in case of a member being attacked all the others should defend it.
This added to the historical isolationism of U.S. diplomacy stopped the country from joining the League of Nations despite its inspiration on President Woodrow Wilson’s Fourteen Points.
