6 apr 1917 anni - The United States declared war on Germany.
There were 2 main reasons for the US to enter
the war. The first is that Germany sunk a
passenger ship and killed 100 civilians. The
second which is the real reason the US joined
was because of the interception of the
Zimmerman telegraph. This was a
telegraph from Germany to Mexico telling
Mexico to attack America. Because of this
America felt the need to join the war.
This also meant America reinstated the
draft for the first time since the civil war.
