because britian needed alot of help because lots of people were dyin an diseases were spreadin an soliders were badly wounded so, america did join in three years after the war began and helped britian beacause the united states of america were bieng called cowards and scared the war would go on alot longer
2 reasons why US joined WWI
1.sinking of innicent us ship 2.germany wanted Mexico to attack the U.S.
Zimmerman note
The United States got involved in World War 1 because of a Zimmerman telegram sent to Mexico detailing German plans against the U.S in which Mexico was conquered by the U.S loosing Arizona, New Mexico, and Texas. The note was sent on April 2 1917 and 4 days later the U.S declared war against Germany.
