if the USA stayed out of WWI, the war could have dragged on much longer and potentially Germany could have been so weakened that the Soviets would have walked in (as they nearly did in 1920, only stopped by the Poles in the Miracle on the Vistula)
Also, a potential war with Mexico could have been in the offing in the 20s if the war dragged on.
