The American public has usually been reluctant to get the country involved in foreign wars, in conflicts they didn´t understood or where they saw no business for the USA. 1914 was not an exception. Public mood changed after the sinking of the British liner Lusitania by a German U-boat in 1915; over 100 American lives were lost. Besides, Americans reacted with anger after the news of a German secret offer to Mexico to help it recover territory ceded to the USA in 1848  spread (the Zimmerman Telegram).
