The US will remain neutral in this war. We can not pick who to back.
German Occupation of Belgium- August 1914
There are fortifications, through Belgium we go!
Sinking of the Lusitania - May 1915
Prepare to be TORPEDOED and have innocent lives taken!
Because the US has citizens from both sides of the conflict, the president Woodrow Wilson chose to stay neutral. Reasons for this were we were doing well already and the war was all the way across the ocean.
Zimmerman Telegram- January 1917
Have you seen this sir?
Germany declared war on France. The Germans, to avoid French Fortifications, had to cross through Belgium. They did this by force and invaded Belgium. The US saw Germany getting stronger so the US sees this as a possible threat.
Unrestricted Submarine Warfare- 1917
LOL! They tried suspending U-Boat warefare! As IF.
In 1815 the British Ocean liner Lusitania is torpedoed by a German submarine. 1,198 people were drowned, including 128 Americans. All of these innocent civilians dead due to Germans led to American support for entering the war.
US economic interest: 1914-joining war
So many things needed by other countries for this war.
The telegram was useful in convincing the American public that it should be sending men to Europe to fight. It proposed a military alliance between Germany and Mexico saying If the United States entered World War I against Germany, Mexico would recover Texas, Arizona, and New Mexico- having an effect on the US joining the war.
I, Count Johann von Bernstorff, offer significant financial aid to Mexico if agreed to enter any future U.S-German conflict as a German ally.
Yes, I am definitely not wanting to back Germany in this war.
Despite the fact many innocent people died on the Lusitania, Germany decided: "The destructive designs of our opponents cannot be expressed more strongly. We have been challenged to fight to the end. We accept the challenge. We stake everything, and we shall be victorious." They will continue to use U-boat warefare.
I know dude. It's gonna win us the war.
The first 2 ½ years of war when the U.S. was a neutral party, the economic boom came primarily from exports. In this time they traded and produced lots of materials for war. Because world war I was the first mechanized war lots of resources were needed and the US could provide that to allies.
