Answer 2

false

Step-by-step explanation:

Beginning July 28, 1914 with Austria-Hungary declaring war on Serbia in retaliation for the assassination of Archduke Franz Ferdinand, a complicated web of alliances plunges the nations of Europe into war within a month. The United States stays politically neutral. Americans entered the war in 1917 by declaring war on Germany. This was due to the attack on Lusitania, the unrestricted submarine warfare on American ships heading to Britain, and Germany encouraging Mexico to attack the USA.
