Which of these caused the united states to become involved in world war i? a) the german invasion of poland b) repeated violation of treaties by japan c) enemy bombing of american military bases d) threats to american security made by germany

Best Answer : C, enemy bombings of military bases because Japan attacked the Pearl Harbor ( Hawwi Navy Base ) when most of the battle ships and carriers where out for practic. The Japenase thought that they should attack and wipe out the battle ships that were guarding or in other words, off duty ships. That bombing made Hiteler mad because he did not want the U.S to be part of the war because they were the world power at that time. ( just like now ) I hope this answer helped you.
