Dr. Martin Luther King Jr. famously said that we would need to tackle three interlocking problems together: racism, militarism, and extreme materialism. A couple of the ways they interact are that militarism promotes racism and racism promotes militarism. War and war propaganda have often fueled and been fueled by racism, xenophobia, religious hatred, and other types of bigotry, and those illnesses persist beyond a war.
Historian Kathleen Belew documents a correlation between the aftermath of war and the rise of white supremacist violence: “If you look, for instance, at the surges in Ku Klux Klan membership, they align more consistently with the return of veterans from combat and the aftermath of war than they do with anti-immigration, populism, economic hardship, or any of the other factors that historians have typically used to explain them.”
Religious bigotry and racism have long been used in promoting wars. Propaganda posters during World War I showed Jesus wearing khaki and sighting down a gun barrel. Karim Karim, an associate professor at Carleton University’s School of Journalism and Communication, writes: “The historically entrenched image of the ‘bad Muslim’ has been quite useful to Western governments planning to attack Muslim-majority lands. If public opinion in their countries can be convinced that Muslims are barbaric and violent, then killing them and destroying their property appears more acceptable.” Christian proselytization is common in the U.S. military, and so is hatred of Muslims. Soldiers have reported to the Military Religious Freedom Foundation that when seeking mental health counseling, they have been sent to chaplains instead who have counseled them to stay on the “battlefield” to “kill Muslims for Christ.”
Religion can be used to encourage the belief that what you are doing is good even if it makes no sense to you. A higher being understands it, even if you don’t. Religion can offer life after death and a belief that you are killing and risking death for the highest possible cause. But religion is not the only group difference that can be used to promote wars. Any difference of culture or language will do, and the power of racism to facilitate the worst sorts of human behavior is well established. Senator Albert J. Beveridge offered the U.S. Senate his own divinely guided rationale for war on the Philippines:
“God has not been preparing the English-speaking and Teutonic peoples for a thousand years for nothing but vain and idle self-contemplation and self-admiration. No! He has made us the master organizers of the world to establish system where chaos reigns.”
The two world wars in Europe, while fought between nations now typically thought of as “white,” involved racism on all sides. The French newspaper La Croix on August 15, 1914, celebrated “the ancient élan of the Gauls, the Romans, and the French resurging within us,” and declared that “The Germans must be purged from the left bank of the Rhine. These infamous hordes must be thrust back within their own frontiers. The Gauls of France and Belgium must repulse the invader with a decisive blow, once and for all. The race war appears.”
A psychiatrist developed a methodology to allow the U.S. Navy to better prepare assassins to kill. It includes techniques, “to get the men to think of the potential enemies they will have to face as inferior forms of life [with films] biased to present the enemy as less than human: the stupidity of local customs is ridiculed, local personalities are presented as evil demigods.”
It is much easier for a U.S. soldier to kill a hadji than a human being, just as it was easier for Nazi troops to kill Untermenschen than real people. William Halsey, who commanded the United States’ naval forces in the South Pacific during World War II, thought of his mission as “Kill Japs, kill Japs, kill more Japs,” and had vowed that when the war was over, the Japanese language would be spoken only in hell.
Nationalism is the most recent, powerful, and mysterious source of mystical devotion aligned with war, and the one that itself grew out of war making. While knights of old would die for their own glory, modern men and women will die for a fluttering piece of colored cloth that itself cares nothing for them. The day after the United States declared war on Spain in 1898, the first state (New York) passed a law requiring that school children salute the U.S. flag.
