Foundations of Liberty: peace 
Essential
A New Approach to US Foreign Policy
By Christopher Preble: "The expansion of state power has occurred in almost every crisis, and at the expense of individual liberty. In short, war is a kind of petri dish for the germ of expanding state power."
Economic Freedom and Peace
"Since before the time of Thucydides, states have used wealth to acquire more territory and to dominate the affairs of their neighbors. Understanding the reasons that the powerful countries of today are less prone to dispute than their predecessors is critical to maintaining the peace and to extending its benefits more broadly."

Government, War, and Libertarianism
By Justin Logan: "Why has the war—and post-9/11 foreign policy generally—been so controversial for libertarians? And now, more than six years after 9/11 and more than five years into the war in Iraq, what can libertarian insights tell us about how we got here and what to do next?"
McCain Talking Too Tough on Russia, China
By Malou Innocent: "There is no question that China and Russia have objectionable policies. China's deplorable human-rights record and Russia's authoritarian structure leave much to be desired. But McCain's policy prescriptions will prevent the U.S. from working with them in areas of common interest, and preclude cooperation in meeting shared threats."
Coyne on Exporting Democracy after War
"Christopher Coyne of West Virginia University and George Mason University's Mercatus Center talks with EconTalk host Russ Roberts about his book, After War: The Political Economy of Exporting Democracy. They talk about the successes and failures of America's attempts to export democracy after a war."
Don't 'Pull an Iraq' in Afghanistan
By Benjamin H. Friedman: "This week at a NATO summit in Bucharest, Romainia, American officials asked Europeans to send more troops to the war in Afghanistan. Leaders in both the Democratic and Republican Parties agree that higher troop levels and a deeper commitment to state-building are the path to victory in Afghanistan. But both sides are wrong, and Iraq shows why."
Who Says the Surge Is Working?
By Terry Michael: "When it comes Iraq, neoconservative true believers have been allowed to set the bar of "success" below ground level. In this, they're aided by media siding with power instead of challenging it, all while congressional Democrats cower in their cloak rooms."
McCain's Consistent Folly on Iraq
By Steve Chapman: "If so, that may not be a plus for McCain. McCain has been consistent about Iraq, in the sense of being consistently wrong. If the American people get a long look at what he's said and a clear picture of our fortunes in Iraq, he may yearn for the days when he was being pilloried for offering "amnesty" to illegal immigrants."
Learning the Right Lessons From Iraq
By Benjamin H. Friedman and Christopher Preble: "By insisting that there was a right way to remake Iraq, we ignore the limits on our power that the enterprise has exposed and risk repeating our mistake. Deposing Saddam Hussein was relatively simple, but creating a new state to rule Iraq was beyond our grasp. Maybe the United States can improve its ability to manage occupations, but the principal lesson Iraq teaches is to avoid them."
Atlas Hugged
Brian Doherty: "As executive vice president of the Cato Institute, Boaz is one of the media's primary go-to guys on libertarian thought and policy. And in his new book, "The Politics of Freedom," a collection of his short-form journalism from the past 25 years, Boaz pushes an interesting and counterintuitive belief about American politics. The political spectrum, he argues, contains a lot more libertarians than the two major party's stances would lead you to believe."
NATO's West Bank Nightmare
By Ted Galen Carpenter: "Washington is sending up a trial balloon about stationing NATO troops as peacekeepers on the West Bank. The Jerusalem Post reports that former NATO supreme commander General James Jones, now the Bush administration's special envoy to the Middle East, is floating the idea to various European countries.
"It is a spectacularly bad idea."
The Fear Factory
By Guy Lawson: "The FBI now has more than 100 task forces devoted exclusively to fighting terrorism. But is the government manufacturing ghosts?"
The AtomicTerrorist: Assessing the Likelyhood
By John Mueller: "A terrorist atomic bomb is commonly held to be the single most serious threat to the national security of the United States. Assessed in appropriate context, that could actually be seen to be a rather cheering conclusion because the likelihood that a terrorist group will come up with an atomic bomb seems to be vanishingly small. Moreover, the degree to which al-Qaeda--the chief demon group and one of the few terrorist groups to see value in striking the United States--has sought, or is capable of, obtaining such a weapon seems to have been substantially exaggerated."
Is The Domestic Terror Threat ‘Overblown’?
By Benjamin H. Friedman: "Time and again, federal officials held press conferences to announce the break-up of a terrorist plot and vaguely described the disaster prevented. The evening news and the headlines repeated their lurid claims. Months later, the inside pages of the papers would report that the plot was not what we were told — and TV doesn’t even bother. The plans have turned out to be unfeasible or preliminary. "
Redefining Success in Iraq
By Christopher Preble: "The surge was certainly successful in one sense: it took sufficient steam out of the "get out now" movement to effectively halt congressional efforts to force a troop withdrawal. It also allowed Sen. McCain to resurrect his moribund campaign. "Thank God [Iraq]'s off the front pages," the leading proponent for the war told reporters on board the Straight Talk Express."
The Terrible 'Ifs'
By Benjamin H. Friedman: "We spend vast amounts on defenses against threats unlikely to affect Americans. Experts, defense officials, and politicians justify the expenditures by saying they are necessary to protect the public from worst case dangers. Those claims ignore what is probable and what defenses cost. They exaggerate the danger our enemies pose and strip resources from more probable dangers, making us less safe."
What to Be Thankful For
By David Boaz: "Not long ago a journalist asked me what freedoms we take for granted in America. Now, I spend most of my time sounding the alarm about the freedoms we're losing. But this was a good opportunity to step back and consider how America is different from much of world history -- and why immigrants still flock here."
Iraqi Allies Deserve Better than Red Tape
By Malou Innocent: "Many Iraqis, desperate to earn decent wages and bring stability to their country, support American forces by working as Arabic interpreters. "Terps" are paid a modest sum, and they enable soldiers to communicate with Iraqi civilians and track down insurgents. But working with the Americans can come at a high cost."
Economics in Many Lessons: A Better Brew for Rwanda
By Donald J. & Karol C. Boudreaux: "In some parts of the long-suffering continent, good things are happening and too few people, in Africa and elsewhere, know about them."
The Case for Restraint
By Barry R. Posen: "If more activism has not produced better policy, what is to be done? The United States should try doing less: It should pursue a grand strategy of restraint. Less is not nothing, however, meaning in essence that the United States should conceive ways to shape rather than to control international politics."
Understanding Insurgency
Malou Innocent, a Foreign Policy Analyst at the Cato Institute, describes the problematic nature of insurgency and argues that fighting them is tricky, and should only be undertaken when vital national interests are at stake. The insurgency in Iraq, she argues, does not qualify.
Inside Track: A Troubling Interventionist Consensus
By Christopher Preble and David Rieff: "Presidential hopefuls and policy wonks debate amongst themselves how to improve America’s effectiveness as world policeman and decry any challenge to that role, as if they believed it to be somehow inscribed in our country’s DNA. We believe that the United States should adopt a fundamentally different approach."
A Dangerous Position on Darfur
By Ted Galen Carpenter and Christopher Preble: "The suffering in Darfur cries out for action, but it is not clear that it calls for military action, much less that U.S. troops should lead the effort. There are dozens of countries that have far greater tangible interests at stake in Darfur than does America, and many of these countries also possess the capacity to deploy forces there."
Taiwan's Defense Budget: How Taipei's Free Riding Risks War
By Justin Logan & Ted Galen Carpenter: "It would be dubious enough for the United States to risk war with an emerging great power like China to defend a small client state, even if that state were making a serious effort to provide for its own defense. It would be even worse to incur that risk on behalf of a client state that is not willing to make a robust defense effort."
Petraeus, the Surge & History
"Many have repeated the claim that Iraq is Vietnam all over again. History never repeats itself exactly, so no example is perfect. But the American surge in Iraq bears a striking and little-noted resemblance to the Germans' ill-fated offensive in the last year of World War I."
Peace on earth? Try free trade among men
"Much of the political violence that remains in the world today is concentrated in the Middle East and Sub-Saharan Africa -- the two regions of the world that are the least integrated into the global economy. Efforts to bring peace to those regions must include lowering their high barriers to trade, foreign investment, and domestic entrepreneurship."
