The American entry into World War I came in April 1917, after two and a half years of efforts by President Woodrow Wilson to keep the United States neutral. Apart from an Anglophile element supporting the British, American public opinion went along with neutrality at first. The sentiment for neutrality was strong among Irish Americans, German Americans and Swedish Americans, as well as among church leaders and women. On the other hand, even before World War I broke out, American opinion toward Germany was already more negative than it was toward any other country in Europe. The citizenry increasingly came to see the German Empire as the villain after news of atrocities in Belgium in 1914, and the sinking of the passenger liner RMS Lusitania in May 1915. Wilson made all the key decisions and kept the economy on a peacetime basis, while allowing banks to make large-scale loans to Britain and France. To preclude making any military threat, President Wilson made only minimal preparations for war and kept the United States Army on its small peacetime basis, despite increasing demands for preparedness. However, he did enlarge the United States Navy.
