Which statements best communicate the main idea of this speech? Check all that apply.
alukav5142 [94]

Answer:

Higher taxes will have a severe impact on citizens.

Explanation:

The growth of Isolationism and nonintervention spurred, leading to high-cost involvement in the war. The government sought to create assurance that the American was not involved in the conflicts.

The act was generally negative because it had no distinction on any victims because it treated them equally and limited the American aid to them and prevented France from the Nazi.
