Explanation:

In 1939, the U.S. held strong isolationist sentiment after WWI, avoiding European conflict. It restricted immigration, ignored the weak League of Nations, and didn't mobilize troops until later. Instead, Congress enforced neutrality via existing/updated neutrality laws.

Answer:

Congress stressed isolationism and passed five neutrality laws
