Red lines and red herrings

Guest post by Daryl G. Press and Jennifer Lind

With reports of chemical weapons use in Syria, many U.S. officials and foreign policy analysts have called for U.S. military intervention there. They quote President Obama's previous statements referring to chemical weapons use as an unacceptable crossing of a "red line." This is unsurprising: Every time analysts and leaders call for war, they warn that inaction will jeopardize America's credibility. What is more surprising, however, is how little evidence there is for this view.

What has actually transpired in Syria remains unclear (especially with a new claim that Syria rebels may have used nerve gas), but the possibility that Syria crossed the administration's "red line" has brought calls for U.S. military action. "The credibility of the United States is on the line," declared Senators John McCain and Lindsey Graham, "not just with Syria, but with Iran, North Korea, and all of our enemies and friends who are watching closely to see whether the president backs up his words with action." (Many others have made similar arguments, for example here and here.)  

To be sure, for a country like the United States -- which seeks to assure allies and deter adversaries around the globe -- credibility is a precious asset. Credibility -- the belief held by others that a country will carry out its threats and promises -- is the difference between deterring attacks and having to wage war to repel them. 

But how do countries build credibility? Those who favor intervention in Syria assert that credibility comes from having a reputation for keeping commitments. The "smoking gun" evidence for this view can allegedly be found in a 1939 speech in which Adolf Hitler explained to his generals why he felt emboldened to invade Poland. He dismissed French and British threats, mocking them for their concessions at the Munich Conference: "Our enemies are worms," he scoffed, "I saw them at Munich." 

Hitler's quote, and the so-called "Munich Analogy," has come to embody the danger of breaking commitments and featured prominently in U.S. decisions to defend South Korea in 1950 and later to fight (and stay) in Vietnam. Since then, the fear of losing credibility helped propel the United States into conflicts in Bosnia, Kosovo, Iraq, and Libya.

The problem is that there's little evidence that supports the view that countries' record for keeping commitments determines their credibility. Jonathan Mercer, in his book Reputation and International Politics, examined a series of crises leading up to World War I and found that backing down did not cause one's adversaries to discount one's credibility. 

In another book, Daryl Press examined a series of Cold War crises between NATO and the Warsaw Pact. From 1958 to 1961, Nikita Khrushchev repeatedly threatened to cut off NATO's access to West Berlin. Each time, the deadlines passed and Khrushchev failed to carry out his threats.

If backing down damages credibility, Khrushchev's credibility should have been plummeting, but the deliberations of American and British leaders show that his credibility steadily grew throughout this period. And a year after the 1961 Berlin confrontation, when the same American decision-makers confronted Khrushchev during the Cuban Missile Crisis, they took his threats very seriously. Senior U.S. leaders were convinced that Khrushchev would respond to any forceful U.S. act against Cuba with an immediate Soviet attack against Berlin. Four years of backing down had not damaged Soviet credibility in the least.

Documents from American and British archives reveal that when NATO leaders tried to assess the credibility of Soviet threats, they didn't focus on the past. Instead, they looked at Khrushchev's current threat and the current circumstances and asked themselves two simple questions. Can he do it? And would it serve his interests?

In the eyes of the Macmillan, Eisenhower, and Kennedy governments, Soviet credibility was growing -- despite Khrushchev's bluster -- simply because Soviet power was expanding. Power and interests in the here-and-now determine credibility, not what one did in different circumstances in the past.

Even the canonical case for reputational arguments -- Hitler's dismissal of French and British threats in 1939 -- shows that credibility stems from power and interests. When Hitler told his generals why the British and French would not oppose him when he invaded Poland, he listed seven reasons, every one of which was about the balance of power. The "worms" quote was a throwaway line after a detailed analysis of the balance of military power and Poland's indefensibility.

Advocates of intervention in Syria worry that a failure to act will embolden U.S. adversaries around the world. But if Kim Jong Un is trying to figure out whether or not the United States would defend South Korea, he will notice that Washington and Seoul have been allies for more than six decades, and that with the rise of China, the United States is increasing its focus on East Asia.  The notion that Kim would interpret U.S. reluctance to stop a humanitarian disaster in Syria as a green light to conquer a major U.S. ally strains credulity.

Similarly, leaders in Tehran assessing U.S. threats to strike their nuclear facilities will weigh America's clear interest in nuclear nonproliferation against the real limitations of airstrikes against Iran's deeply buried nuclear facilities. American reluctance to support various extremist rebels in Syria is unlikely to enter into Iran's calculus.

As the civil war in Syria unfolds, the United States may eventually decide to intervene. U.S. officials and foreign policy analysts might make the case (which we disagree with) to join the fighting in order to stop the humanitarian disaster, to contain regional instability, or to secure U.S. influence with the post-Assad Syrian government. But the case for U.S. military intervention should not rest on a bogus theory about signaling resolve to Khamenei and Kim.  American credibility lies elsewhere.
