In the United States public opinion was outraged; war talk was rife and pro-German elements kept quiet. The key issue was the savagery in the German failure to allow passengers to escape on life boats as required by international law. President Woodrow Wilson refused to immediately declare war—his main goal was to negotiate an end to the war. During the weeks after the sinking, the issue was hotly debated within the U.S. government, and correspondence was exchanged between the U.S. and German governments. German Foreign Minister Von Jagow continued to argue that "Lusitania" was a legitimate military target, as she was listed as an armed merchant cruiser, she was using neutral flags and she had been ordered to ram submarines – in blatant contravention of the Cruiser Rules.
