In fact, there were several small, bloody shooting wars going on around the world during the Pox. These were stupid affairs—wastes of life and treasure. They were fought, ostensibly, to defend against vicious foreign enemies. All too often, they were actually fought because inadequate leaders did not know what else to do. Such leaders knew that they could depend on fear, suspicion, hatred, need, and greed to arouse patriotic support for war.
