The authors hold that the law of neutrality as developed in modern times is too precious a heritage to be thrown away, especially for such a poor substitute as "collective security" -- which they find to be the very antithesis of real neutrality. Most of their volume consists of a history of American "unneutrality" from 1914 to 1917. Their interpretation of our policy during those years pictures Wilson and most of his advisers as far from neutral in thought and deed. Like Mr. Hallgren's work, this book shows the growing disillusionment with our neutrality policy.
