Having just completed a trilogy of books about decisive moments in the Cold War, I am bemused by the "Who lost the Arab Spring?" debate that suddenly seems to be gripping Washington. Like many foreign policy controversies, this one is driven more by the domestic political agenda -- and specifically the presidential election in November -- than informed analysis of actual events.

To hear many Republicans talk, Barack Obama is to blame for the sudden upsurge of violence in the Arab world that claimed the life of our brave ambassador to Libya. The president's repeated "apologies" for American values have encouraged the extremists in Cairo, Benghazi, and elsewhere.  

This kind of argument is similar to the "Who lost China?" debate that followed the Chinese Communist seizure of power in 1949.  It supposes that China -- or the Arab Spring, in this case -- was ours to lose. The reality, of course, is that a U.S. president has very little influence over what happens in the paddy-fields of China or the streets of Cairo or the bazaars of Baghdad, unless he chooses to send in the First Armored Division. And as we have seen in Iraq, the forceful exercise of presidential power does not always produce the desired results.

A central theme of my three Cold War books -- Down with Big Brother, One Minute to Midnight, and Six Months in 1945 -- is the role of political leadership versus the chaotic forces of history. There are moments -- the Cuban missile crisis is a good example -- when the fate of the world hangs on the decisions and actions of a few individuals. More generally, however, the politicians are left scrambling to keep pace with events that are beyond their ability to control.

The most successful leaders are those who understand this fundamental truth, but keep plugging away all the same. At the height of the Civil War, Abraham Lincoln lamented that he did not control events. "Events control me." And yet he somehow steered the country through the greatest crisis in its history. JFK expressed very similar sentiments during the Cuban missile crisis.

Of course, there are different types of foreign policy crises. As I describe in One Minute to Midnight, the missile crisis is a good example of a crisis that Kennedy and Khrushchev helped to create. This is a rare case where two men actually had the power to blow up the world. Through a series of mistakes and miscalculations, Kennedy and Khrushchev led the world to the brink of nuclear destruction -- but also had the wisdom to lead it back from the brink.

The onset of the Cold War was a different kind of crisis, more akin to the kind of crisis we are facing in the Middle East right now. In my forthcoming book, Six Months in 1945, I conclude that neither FDR, nor Stalin, nor Churchill, nor Truman wanted the Cold War. They sought to postpone it, for as long as they could. But it happened anyway -- because of the larger forces of history identified by Alexis de Tocqueville more than a century before. 

"Their starting point is different and their courses are not the same," de Tocqueville wrote of Russia and America in 1839, "yet each of them seems marked out by the will of Heaven to sway the destinies of half the globe." I think we are seeing a historical upheaval of similar dimensions play out before our eyes on the streets of the Arab world.
