No, they were to help us stop from selling ammunition, guns, etc, to Europe and Asia, for the first Neutrality Act, to fuel the sense of isolationism for the United States, then the second act forbidding United States citizens from traveling on American merchant ships to prevent transporting weapons more so. But even with all the neutrality acts, in 1941 the Lend-Lease being sent through, giving permission to help aid the Allies, making the Neutrality Acts a Bust.
