Impact of America Entry into World War 1 It’s just ONE paragraph, not a full page essay:
What impact did America’s entry into WWI have on the overall Allied effort? After the rupture of diplomatic relations with Germany on Feb. 3, 1917, events pushed the United States inexorably along the road to war. Using his authority as commander in chief, Wilson on March 9 ordered the arming of American merchant ships so that they could defend themselves against U-boat attacks. German submarines sank three U.S. merchant ships during March 16–18 with heavy loss of life. The presidential declaration of war followed immediately. The entry of the United States was the turning point of the war because it made the eventual defeat of Germany possible.
