The statement that best evaluates President Franklin Roosevelt’s strategies for persuading more Americans to abandon isolationist policies after the beginning of World War II in Europe is:
Roosevelt assured Americans that sending weapons to European nations attacked by Germany would prevent further advancement of Nazi aggression.
This reflects Roosevelt's approach to fostering support for interventions such as the Lend-Lease Act, as he aimed to bolster allied nations while framing the assistance as a way to protect American interests and prevent the spread of fascist aggression.
