The World at War

More than 100 million soldiers and civilians are estimated to have died during the international and civil wars of the twentieth century (Leitenberg, 2006). Although this is almost an unimaginable number, there is cause for some hope, even as there is also cause for despair.

The hope arises from historical evidence that the number of international wars, civil wars, and other types of armed conflict has in fact declined over the centuries, with the number in the past half-century much smaller than in centuries past (Pinker, 2012). Reflecting this decline, a smaller percentage of the world’s population died in armed conflict during the past century than in earlier eras.

To illustrate this trend, compare two periods of history (Pinker, 2012). The first is the thirteenth century, when the Mongol Empire under the initial leadership of Genghis Khan became an empire in Asia and Eastern Europe through wars and conquest in which it killed 40 million people. The second period is 1939–1945, when World War II killed 55 million people. Although 55 million is more than 40 million, the world’s population in the thirteenth century was only one-seventh its population during the World War II period. A quick calculation shows that about 11 percent of the world’s population died from the Mongolian wars, while 2 percent died from World War II. In terms of the risk of dying in war, then, the Mongolian wars were five times more deadly than World War II.

Although World War II killed an estimated 55 million people, a smaller percentage of the world’s population died in armed conflict during the twentieth century than in earlier eras.

Looking further back in world history, the death rate in prehistoric times from tribal warfare was extremely high. If this high rate had held true during the twentieth century, 2 billion people would have died in twentieth-century wars rather than the 100 million who did die (Pinker, 2012). Although wars, other armed conflicts, terrorism, and genocide certainly continue, and 100 million is a terribly high number of deaths, the world overall is in fact more peaceful now than in the past.

That is the good news and the cause for hope. The cause for despair is twofold. First, war, terrorism, genocide, and other armed conflicts do continue. Even if they are less frequent and less deadly than in the past, that is of little comfort to the tens of millions of people around the world during the past century who died or otherwise suffered in war and other armed conflict and who live in fear today of becoming a victim of armed conflict.

Second, the world today is a much more dangerous place than in the past because of the existence of nuclear weapons. The thirteenth-century Mongolians killed their 40 million with battleaxes and other crude weapons; the World War II deaths resulted from gunfire and conventional bombs. At the end of that war, however, the nuclear age began when the United States dropped two atomic weapons on Japan that killed tens of thousands instantly and tens of thousands more from radiation exposure.

Those two weapons were tiny in both number and size compared to nuclear weapons today. More than 20,000 nuclear warheads now exist; 4,800 are operational and almost 2,000 (held by the United States and Russia) are on high alert, ready to be used at any time (Federation of American Scientists, 2011). Each of these warheads is an average of at least twenty times more powerful than each of the atomic bombs that decimated Japan. The Union of Concerned Scientists (2009) summarizes their danger bluntly: “Nuclear weapons remain the greatest and most immediate threat to human civilization.” However more peaceful the world is today, it could easily end at any moment.

The United States at War

If we say the history of the United States has been written in war, that is not too much of an exaggeration. The United States, of course, began with the colonial war against England. The American Civil War, also called the War Between the States, then tore it apart less than a century later. Between 1861 and 1865, at least 618,000 and perhaps as many as 750,000 soldiers in both the Union and the Confederacy died on the battlefield or from disease. The minimum estimate almost matches the number of American deaths in all the other wars the United States has fought, and the maximum estimate greatly exceeds this number (see Table 16.2 “US Participation in Major Wars”).

The United States has been at war in one-fifth of the years it has existed (Bumiller, 2010). Between the end of the colonial period and 1993, the US military was involved in at least 234 declared wars, undeclared wars, or other situations abroad involving actual or potential armed conflict (Collier, 1993). Since 1993, US armed forces have waged war in Iraq and in Afghanistan and also joined international military operations in such countries as Bosnia, Herzegovina, and Libya. By any measure, then, the US military has played a fundamental role, for better or worse, in the nation’s foreign affairs historically and also today. Supporters of this role say the military has both protected and advanced the political and economic interests of the United States, while critics, as we have seen, charge that the military has been an instrument of imperialism.

Explaining War

The enormity of war has long stimulated scholarly interest in why humans wage war (Levy & Thompson, 2010). A popular explanation for war derives from evolutionary biology. According to this argument, war is part of our genetic heritage because the humans who survived tens of thousands of years ago were those who were most able, by virtue of their temperament and physicality, to take needed resources from other humans they attacked and to defend themselves from attackers. In this manner, a genetic tendency for physical aggression and warfare developed and thus still exists today. In support of this evolutionary argument, some scientists note that chimpanzees and other primates also engage in group aggression against others of their species (Wrangham, 2004).

However, other scientists dispute the evolutionary explanation for several reasons (Begley, 2009). First, the human brain is far more advanced than the brains of other primates, and genetic instincts that might drive these primates’ behavior do not necessarily drive human behavior. Second, many societies studied by anthropologists have been very peaceful, suggesting that a tendency to warfare is more cultural than biological. Third, most people are not violent, and most soldiers have to be resocialized (in boot camp or its equivalent) to overcome their deep moral convictions against killing. If warlike tendencies were part of human genetic heritage, these convictions would not exist.

Scholars have attempted to explain why human beings wage war. A popular explanation comes from the field of evolutionary biology and claims that a tendency toward warfare is hardwired into our genetic heritage because it conferred certain evolutionary advantages.

Civilians: The Casualties of War

Table 16.2 “US Participation in Major Wars” listed the hundreds of thousands of troop deaths in American wars. The nation rightly grieved these deaths when they occurred and built monuments, such as the Korean and Vietnam veterans memorials in Washington, DC, that list the names of the dead.

John Tirman, director of the Center for International Studies at the Massachusetts Institute of Technology, worries that Americans have neglected the civilian victims of war. He applauds the Korean and Vietnam memorials in Washington, but he laments that “neither mentions the people of those countries who perished in the conflicts” (Tirman, 2012, p. B01). “When it comes to our wars overseas,” he adds, “concern for the victims is limited to U.S. troops.”

Tirman notes that approximately 6 million civilians and soldiers died in the Korean, Vietnam/Indochina, Iraq, and Afghanistan wars. Most of these victims were civilians, and most of these civilian deaths were the result of actions by the United States and its allies. These deaths stemmed from bombs and other weapons that went astray, from orders by military and political leaders to drop millions upon millions of bombs on civilian areas, and sometimes from atrocities committed by US personnel. In World War II, Tirman adds, the United States dropped two atomic bombs that killed tens of thousands of civilians, and it joined its allies in the carpet bombing of German and Japanese cities that also killed hundreds of thousands.

The two atomic bombs dropped by the United States over Japan during World War II killed tens of thousands of civilians. Scholar John Tirman worries that Americans have generally ignored the civilian victims of US wars.

Tirman (2012) acknowledges that the carpet bombing, atomic bombing, and other actions in World War II that killed hundreds of thousands of civilians may have had strategic purposes, and the morality of these actions remains hotly debated today. But he also notes that the Korean and Vietnam wars included many atrocities committed by American troops against civilians. To be blunt, American troops simply shot untold hundreds of Korean and Vietnamese civilians in cold blood.

Tirman describes one Korean incident in which machine gun fire from US warplanes killed about one hundred civilian refugees who were resting on a road. The remaining several hundred refugees hid and were shot at for three days by US ground soldiers. Tirman (2012, p. 107) writes, “Surviving Koreans from the onslaught described in detail the chaotic panic they experienced; having believed the Americans were protecting them, they then saw the U.S. troops fire indiscriminately at men, women, and children at the scene.” At the end of the three days, about four hundred civilians lay dead.

In Vietnam, Tirman writes, American troops and planes routinely razed villages to the ground, killing villagers indiscriminately, and then evacuated any survivors. Once they were evacuated, their villages were designated “free fire zones,” and then often bombed indiscriminately once again, killing any villagers who managed to remain in these zones despite the evacuations. All these killings were outright slaughter.

In one example of what Tirman (2011, p. 153) calls a typical massacre, US soldiers arrived at a village that had just been bombed and ordered surviving residents to gather at the center of the town. After they did so, US ground troops shot them and left a pile of dead bodies that included twenty-one children. As this brief discussion indicates, although the massacre of 347 Vietnamese at the hamlet of My Lai is undoubtedly the Vietnam massacre that is best known (and perhaps the only known) to the American public, massacres were far from rare and in fact were rather common.

A central part of US military strategy in Vietnam involved destroying rice fields and the rest of the countryside to make it difficult for the Vietcong forces to engage in guerrilla warfare. To do so, it routinely deployed chemical weapons such as Agent Orange (dioxin, a known carcinogen), napalm, and white phosphorous. Planes sprayed and bombed these chemicals. These actions did destroy the countryside, but they also destroyed humans. The Note 16.13 “Children and Our Future” box discusses this problem in greater detail.

Veterans: The Casualties of War

The attention just given to civilians should in no way obscure or minimize the fact that veterans are also casualties of war. The Korean and Vietnam veterans’ memorials in the nation’s capital and so many other memorials across the nation remind us of the hundreds of thousands of brave men and women who have died serving their country. But veterans are casualties in other ways, as the news story that began this chapter made clear. They suffer terrible physical and mental wounds that can maim them for life (Dao, 2012).

Veterans of the Vietnam War came back to a nation that often did not greet them as heroes. Many came back addicted to heroin and other drugs, many were unemployed, and many became homeless. Many veterans of the wars in Iraq and Afghanistan have also come back home with these problems. Their unemployment rate was 13.1 percent in December 2011, compared to only 8.5 percent for the general public; the unemployment rate for veterans ages 20–24 was near 30 percent (Dewan, 2011; Zornick, 2012). Many veterans are experiencing posttraumatic stress disorder (PTSD), marked by nightmares, panic attacks, and other symptoms (Dao, 2012). Veterans with PTSD often end up with problems in their marriages or other relationships and are more likely to commit violence against their spouses or partners. When these problems occur, they may ironically worsen the psychological state of these veterans.

A related problem is suicide. For every 100,000 Iraq and Afghanistan veterans who receive health care from the Veterans Administration, 38 have killed themselves. The suicide rate of the general population is only 11.3 deaths per 100,000 population. The suicide rate of Iraq and Afghanistan veterans is thus more than three times higher than that of the general public (Martinez & Bingham, 2011).

Veterans of the Iraq and Afghanistan War have a higher suicide rate than that of the general public.

Evidence from a national survey of Iraq and Afghanistan veterans underscores the problems they face (Pew Research Center, 2011). Almost half said their family relations were strained and that they often felt irritable or angry; 44 percent said they had problems reentering civilian life; and 37 percent said they had suffered from PTSD.

One Iraq veteran with these problems is Tom Marcum, who came home with a brain injury, PTSD, and fits of violence and short-term memory loss. His wife April had to quit her teaching job to take care of him, and their life savings slowly dwindled. April missed the man she used to know: “The biggest loss is the loss of the man I married. His body’s here, but his mind is not here anymore. I see glimpses of him, but he’s not who he was” (Einhorn, 2011, p. A12).

As the Marcums’ situation indicates, spouses and other family members of veterans also are casualties of war. Indeed, the Marcums’ situation is far from rare among the families of the 2 million veterans of the Iraq and Afghanistan wars. As a news report summarized these families’ experience, “Ms. Marcum has joined a growing community of spouses, parents and partners who, confronted with damaged loved ones returning from war who can no longer do for themselves, drop most everything in their own lives to care for them. Jobs, hobbies, friends, even parental obligations to young children fall by the wayside. Families go through savings and older parents dip into retirement funds” (Einhorn, 2011, p. A12).

Families of deployed troops also face many difficulties. There is the natural fear that loved ones will never return from their overseas involvement in armed conflict. This fear can take a psychological toll on all members of these families, but perhaps especially on children. One teenager recalled the tensions that arose when his father was in Iraq: “I was in eighth grade when my dad deployed to Iraq. A kid walked up to me and said, ‘Your dad’s a baby killer.’ I didn’t handle that well. We both wound up suspended for that one” (Ashton, 2011).

A recent study found that adolescents with a deployed parent are more likely than those with civilian parents to feel depressed and suicidal. They are also more likely to engage in drug use and binge drinking. Reflecting on these findings, an author of the study said, “It’s really time to focus on the children that are left behind” (Ashton, 2011).

Other Impacts of War

When we think of the impact of war, the consequences for civilians and veterans as just discussed come most readily to mind. But not all civilians are affected equally. One of the many sad truisms of war is that its impact on a society is greatest when the war takes place within the society’s boundaries. For example, the Iraq war that began in 2003 involved two countries more than any others, the United States and Iraq. Because it took place in Iraq, many more Iraqis than Americans died or were wounded, and the war certainly affected Iraqi society—its infrastructure, economy, natural resources, and so forth—far more than it affected American society. Most Americans continued to live their normal lives, whereas most Iraqis had to struggle to survive the many ravages of war.

War also has impact beyond the consequences for civilians and veterans. As historians and political scientists have often described, wars have a significant economic and political impact. Many examples of this impact exist, but one well-known example involves the defeat of Germany in World War I, which led to a worsening economy during the next decade that in turn helped fuel the rise of Hitler.

War can also change a nation’s political structure in obvious ways, as when the winning nation forces a new political system and leadership on the losing nation. Other political and economic changes brought by war are less obvious. World War I again provides an interesting example of such changes. Before the war, violent labor strikes were common in Britain and other European nations. When the war began, a sort of truce developed between management and labor, as workers wanted to appear patriotic by supporting the war effort and hoped that they would win important labor rights for doing so. Although the truce later dissolved and labor-management conflict resumed, labor eventually won some limited rights thanks partly to its support for the war. As a historian summarized this connection, “By the end of the war, labor’s wartime mobilization and participation had increased its relative power within European societies. As a result, and despite the fact that endeavors to reward labor for its wartime cooperation were, in general, provisional, partial, and half-hearted, it was nonetheless the case that labor achieved some real gains” (Halperin, 2004, p. 155).

Other types of less obvious social changes have also resulted from various wars. For example, the deaths of so many soldiers during the American Civil War left many wives and mothers without their family’s major breadwinner. Their poverty forced many of these women to turn to prostitution to earn an income, resulting in a rise in prostitution after the war (Rafter, 1990). Some eighty years later, the involvement of African Americans in the US armed forces during World War II helped begin the racial desegregation of the military. This change is widely credited with helping spur the hopes of southern African Americans that racial desegregation would someday occur in their hometowns (McKeeby, 2008).

Militarism and the US Military Budget

As discussed earlier, President Eisenhower eloquently warned about the influence of the US military and the size of the military budget. The defense industry remains a powerful force in the US economy six decades after Eisenhower issued his warning, and US military spending continues unabated. In 2011, military spending (defense outlays by the Department of Defense and certain other agencies; outlays include costs for the Iraq and Afghanistan wars) according to the government was approximately $768 billion. Defense outlays rose by 85 percent beyond inflation between 2000 and 2011.

The US Military Budget in International Perspective

However it is calculated, the US military budget is by far the highest in the world and in fact accounts for 43 percent of the world’s military spending. In 2010, the US official military budget (defense outlays only) was $698 billion. China ranked a distant second at $119 billion, followed by the United Kingdom at $60 billion and France at $49 billion (see Figure 16.3 “International Military Spending, 2010”).

Lessons from Other Societies

Guns or Butter?

“Guns versus butter” is a macroeconomics phrase that illustrates the dilemma that nations face in deciding their spending priorities. The more they spend on their military (guns), the less they can spend on food for their poor and other domestic needs (butter).

In making this very important decision, Europe has chosen butter over guns. The wealthy European countries that compose the bulk of the Organization for Economic Cooperation and Development (OECD), an international consortium, spend 2.5 percent of their total economy (gross domestic product, or GDP) on their militaries. In contrast, the United States spends 5.1 percent of its economy on its base military budget, which does not include costs for veterans’ benefits, for the Iraq and Afghanistan wars, and military spending that falls outside the Pentagon’s budget.

The European nations’ decisions to limit their military spending allows more spending for social needs. As a result, observes one economics writer, most Europeans have “universal health care, deeply subsidized education (including free university tuition in many countries), modern infrastructure, good mass transit, and far less poverty” than the United States has. Perhaps worse, the United States ranks last among the world’s twenty wealthiest democracies in life expectancy and infant mortality and also ranks worst in the risk of dying before age 60. In addition, half of American children need food stamps at some time before becoming adults, while this problem is far rarer in Europe.

Compared to Europe, then, the United States has chosen guns over butter, leaving far less money for its social needs. As an economics writer wryly noted, “So remember to take pride in American power, and remember that it comes at a very high price.” In making this classic macroeconomics decision, the United States has much to learn from the wealthy nations of Europe.

“A Theft from Those Who Hunger and Are Not Fed”

Oscar Arias, a former president of Costa Rica and a winner of the Nobel Peace Prize, echoed these famous words from President Eisenhower when he wrote a decade ago that US military spending took money away from important domestic needs. “Americans are hurt,” he warned, “when the defense budget squanders money that could be used to repair schools or to guarantee universal health care” (Arias, 1999, p. A19).

The $300 million cost of each F-35 fighter aircraft could pay for the salaries of 10,000 new teachers.

Since Arias wrote these words, the United States has spent more than $5.5 trillion on defense outlays in constant dollars (see Figure 16.3 “International Military Spending, 2010”), including $1.3 trillion on the wars in Iraq and Afghanistan. Cost equivalencies illustrate what is lost when so much money is spent on the military, especially on weapons systems that do not work and are not needed.

For example, the F-35 fighter aircraft has been plagued with “management problems, huge cost-overruns, [and] substantial performance shortfalls,” according to a recent news report (Kaplan, 2012). Each F-35 costs about $300 million. This same sum could be used to pay the salaries of 10,000 new teachers earning $30,000 per year or to build twenty elementary schools at a cost of $15 million each. In another example, the Navy is designing a new series of nuclear submarines, with construction planned to start in 2019. The Navy plans to purchase twelve of these submarines. Each submarine is projected to cost more than $8 billion to build and another $21 billion in constant dollars in operation and maintenance costs over its lifetime (Castelli, 2012). This $29 billion sum for each submarine during its lifetime could provide 5.8 million scholarships worth $5,000 each to low- and middle-income high school students to help them pay for college.

The wars in Iraq and Afghanistan provide additional examples of “a theft from those who hunger and are not fed.” These wars cost the United States about $1.3 trillion through 2012, for an average of more than $100 billion annually (Harrison, 2012). This same yearly amount could have paid for one year’s worth (California cost figures) of all of the following (National Priorities Project, 2012):

• 146,000 police officers
• 9.5 million children receiving low-income health care (Medicaid)
• 1.7 million students receiving full-tuition scholarships at state universities
• 1.6 million Head Start slots for children
• 179,000 elementary school teachers
• 162,000 firefighters
• 2.5 million Pell Grants of $5,550 each

All these figures demonstrate that war and preparation for war indeed have a heavy human cost, not only in the numbers of dead and wounded, but also in the diversion of funds from important social functions and needs.
