Question

how did the united states demonstrate its isolationist policy before world war ii?
by avoiding alliances and other international relationships
by encouraging alliances and international relationships
by avoiding friendships with other foreign countries
by encouraging independence among states in the us

Explanation:

Isolationism in U.S. pre-WWII foreign policy centered on staying out of European and global conflicts by steering clear of formal alliances and deep international commitments that could draw the nation into war. The incorrect options contradict isolationism: encouraging alliances is the opposite, avoiding all foreign friendships is an extreme misrepresentation (the U.S. still had trade ties), and encouraging U.S. state independence is unrelated to foreign policy isolationism.

Answer:

by avoiding alliances and other international relationships
