Answer: The sinking of the ship Lusitania, economic reasons, the naval war of Germany.
Explanation:
And if the sinking of the American ship Lusitania did not immediately bring the united states into the war, a lot of dissatisfaction of the American public towards the Germans was created. Lusitania is a sunken civilian ship that belonged to the United States during the First World War.
Economic reasons are the biggest factor. France and Britain quadrupled arms imports from the United States during the war. As the war progressed, there was a danger that Britain and France would lose, in which case they would not repay the loan for the purchased weapons. That prompted Wilson's government to go to war.
In 1917, Germany decided on total naval war. Some American merchant ships were sunk in those circumstances, thus violating the agreement on neutrality with the United States.
