What else can you think of?

Yes, there are several instances in history where language played a crucial role in creating a significant impact. One notable example, as you mentioned, is the involvement of Navajo speakers in World War II.

They used their native language, which was incredibly complex and had not been previously documented, to create an unbreakable code that the enemy forces could not decipher. This had a profound effect on the war efforts of the United States.
