Think Again: War
World peace could be closer than you think.

"The World Is a More Violent Place Than It Used to Be."
No way. The early 21st century seems awash in wars: the conflicts in Afghanistan and Iraq, street battles in Somalia, Islamist insurgencies in Pakistan, massacres in the Congo, genocidalcampaigns in Sudan. All in all, regular fighting is taking place in 18 wars around the globe today. Public opinion reflects this sense of an ever more dangerous world: One survey a few years ago found that 60 percent of Americans considered a third world war likely. Expectations for the new century were bleak even before the attacks of Sept. 11, 2001, and their bloody aftermath: Politicalscientist James G. Blight and former U.S. Defense Secretary Robert McNamara suggested earlier that year that we could look forward to an average of 3 million war deaths per year worldwide in the 21st century.
So far they haven't even been close. In fact, the last decade has seenfewer war deaths than any decade in the past 100 years, based on data compiled by researchers Bethany Lacina and Nils PetterGleditsch of the Peace Research Institute Oslo. Worldwide, deaths caused directly by war-related violence in the new century have averaged about 55,000 per year, just over half of what they were in the 1990s (100,000 a year), a third of what they were during the Cold War (180,000 a year from 1950 to 1989), and a hundredth of what they were in World War II. If you factor in the growing globalpopulation, which has nearly quadrupled in the last century, the decrease is even sharper. Far from being an age of killer anarchy, the 20 years since the Cold War ended have been an era of rapid progress toward peace.
Armed conflict has declined in large part because armed conflict has fundamentally changed. Wars between big national armies all but disappeared along with the Cold War, taking with themthe most horrific kinds of mass destruction. Today's asymmetrical guerrilla wars may be intractable and nasty, but they will never produce anything like the siege of Leningrad. The last conflict between two great powers, the Korean War, effectively ended nearly 60 years ago. The last sustained territorial war between two regular armies, Ethiopia and Eritrea, ended a decade ago. Even civil wars,though a persistent evil, are less common than in the past; there were about a quarter fewer in 2007 than in 1990.
If the world feels like a more violent place than it actually is, that's because there's more information about wars -- not more wars themselves. Once-remote battles and war crimes now regularly make it onto our TV and computer screens, and in more or less real time. Cell-phone camerashave turned citizens into reporters in many war zones. Societal norms about what to make of this information have also changed. As Harvard University psychologist Steven Pinker has noted, "The decline of violent behavior has been paralleled by a decline in attitudes that tolerate or glorify violence," so that we see today's atrocities -- though mild by historical standards -- as "signs of how lowour behavior can sink, not of how high our standards have risen."

"America Is Fighting More Wars Than Ever."
Yes and no. Clearly, the United States has been on a war footing ever since 9/11, with a still-ongoing war in Afghanistan that has surpassed the Vietnam War as the longest conflict in American history and a pre-emptive war in Iraq that proved to be longer, bloodier, andmore expensive than anyone expected. Add the current NATO intervention in Libya and drone campaigns in Pakistan, Somalia, and Yemen, and it's no wonder that U.S. military spending has grown more than 80 percent in real terms over the last decade. At $675 billion this year, it's now 30 percent higher than what it was at the end of the Cold War.
But though the conflicts of the post-9/11 era may be...
