Want effect did the zimmerman telegram have in the USA

The Zimmerman telegram was an intercepted message from Germany to Mexico. It was encrypted but the message was decoded by American officials revealing Germany's intent to ask Mexico for assistance in engaging war with the USA. Obviously, this was not something the USA would like at all as it basically meant Germany wanted to go to war with the USA. This was a factor into why America eventually joined World War 1 and it began the hate for Germany shown in this period.
