The Palmer Raids contributed to the power of J. Edgar Hoover, as he was one of the leaders of the operations.

Explanation:

The Palmer Raids were the attempts by the United States Department of Justice to arrest and expel radical leftists and anarchists during Alexander Mitchell Palmer's term as Attorney General of the United States. Raids and arrests took place in November 1919 and January 1920 in the context of Red Scare, and were led by J. Edgar Hoover. Although more than 500 foreign citizens have been expelled, including a number of prominent left-wing leaders, Palmer's work had been slowed down by Department of Labor officials who, being responsible for the evictions, had opposed his methods.

for the united states of america, 1945 to 1964 was a time of high economic growth and general prosperity. it was also a time of confrontation as the capitalist united states and its allies politically opposed the soviet union and other communist countries; the cold war had begun.

explanation:

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.
