United States entry into World War 1

Research Question

Was the decision for the US to enter WW1 following the sinking of the Lusitania justified?


Based on our Multiple Attribute Decision Model analysis, we concluded that the original decision for the United States to enter World War 1 after the sinking of the Lusitania was an appropriate decision.


This topic is important because World War 1 was a major turning point in world history as it set in motion many events that started World War 2 and changed the political climate of several European countries.
Germany had set up a war zone in the waters surrounding the United Kingdom and Ireland in response to blockades imposed by Britain on Germany from 1914 that remained in effect until the end of the war. The German blockades consisted of U-Boats that were instructed to sink ships suspected of carrying any supplies for the Allies' war efforts. America had maintained a stance of relative neutrality up until the sinking of the Lusitania in 1915, which caused the death of 128 American citizens. The Lusitania was a civilian ship that Germans had a reason to believe was carrying munitions to Britain, unbeknownst to the passengers on board. Americans and the British were outraged by this act and it caused the British to implore the United States to become involved. The general public and President Woodrow Wilson were against joining the war and instead opted to negotiate with Germany, citing that unrestricted submarine warfare was a violation of Americans' rights. When Germany was found to be engaging in unrestricted submarine warfare again in 1917 and Britain presented the United States with a telegram detailing Germany's plans to ally with Mexico and attack America, the United States declared war on Germany.
