The Tularosa ditch war was about water. The settlers of New Mexico were at war because water was always an important and not easily obtained commodity in New Mexico because of the immense heat and drought. People who were original inhabitants were at war with the English population that was moving in because water was scarce as it was without them.
The media helped promote nationalism and propaganda furthering war efforts. Communications made it easier to broadcast announcements and deliver secret messages (Ex: Fat man and Little boy-Named after two atomic bombs used for the bombing of Hiroshima and Nagasaki).
