To find an historical perspective about the 20th century it would be best to consult

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.

what are two things that greatly the american economy after the war? the huge buildup of u.s. military the beginning of the korean conflict the creation of the gi bill the marshall plan for nations
