New Jersey on 30 July 1916, and to the Kingsland explosion on 11 January 1917 in present-day Lyndhurst, New Jersey. Crucially, by the spring of 1917, President Wilson's official commitment to neutrality had finally unraveled. Wilson realized he needed to enter the war in order to shape the peace and implement his vision for a League of Nations at the Paris Peace Conference. Public opinion American public opinion was divided, with most Americans until early 1917 largely of the opinion that the United States should stay out of the war. Opinion changed gradually, partly in response to German actions in Belgium and the Lusitania, partly as German Americans lost influence, and partly in response to Wilson's position that America had to play a role to make the world safe for democracy. In the general public, there was little if any support for entering the war on the side of the German Empire.

In Eastern cities a new "Preparedness" movement emerged. It argued that the United States needed to build up immediately strong naval and land forces for defensive purposes; an unspoken assumption was that America
