EXPLANATIONS BELOW
Concept note-1: -The entry of the United States was the turning point of the war, because it made the eventual defeat of Germany possible. It had been foreseen in 1916 that if the United States went to war, the Allies’ military effort against Germany would be upheld by U.S. supplies and by enormous extensions of credit.
Concept note-2: -The American Expeditionary Forces arrived in Europe in 1917 and helped turn the tide in favor of Britain and France, leading to an Allied victory over Germany and Austria in November 1918. By the time of the armistice, more than four million Americans had served in the armed forces and 116, 708 had lost their lives.
Concept note-3: -The experience of World War I had a major impact on US domestic politics, culture, and society. Women achieved the right to vote, while other groups of American citizens were subject to systematic repression.
Concept note-4: -Germany’s resumption of submarine attacks on passenger and merchant ships in 1917 became the primary motivation behind Wilson’s decision to lead the United States into World War I.
