The United States never officially declared themselves neutral during the Second World War. Instead, they looked back the World War One to see what dragged them into that conflict. It was determined that trading with the warring nations at the time was what brought them into the war. To make sure that American soldiers were never again dragged into a European conflict they passed a series of laws known as the Neutrality Acts. The first Neutrality Act, stating that the United States could not trade arms and other war materials to any party participating in a war, was passed in 1935. So, in essence, this would be the first year the United States declared their neutrality. The United States passed more Neutrality Acts in 1936, 1937, and 1939. So, you could debate that the US declared their neutrality four times prior to their entering of the Second World War.
