Newsweek’s newest columnist, British historian Niall Ferguson, writes that President Obama’s national security team was caught totally by surprise during the recent sequence of events in Egypt, a crisis that President Nixon and Dr. Kissinger would have ultimately been prepared for after they studied the country, deliberated on the multiple scenarios of possible changes in power, and devised a grand strategy for the region:

The best national-security advisers have combined deep knowledge of international relations with an ability to play the Machiavellian Beltway game, which means competing for the president’s ear against the other would-be players in the policymaking process: not only the defense secretary but also the secretary of state and the head of the Central Intelligence Agency. No one has ever done this better than Henry Kissinger. But the crucial thing about Kissinger as national-security adviser was not the speed with which he learned the dark arts of interdepartmental turf warfare. It was the skill with which he, in partnership with Richard Nixon, forged a grand strategy for the United States at a time of alarming geopolitical instability.

The essence of that strategy was, first, to prioritize (for example, détente with the Soviets before human-rights issues within the USSR) and then to exert pressure by deliberately linking key issues. In their hardest task—salvaging peace with honor in Indochina by preserving the independence of South Vietnam—Nixon and Kissinger ultimately could not succeed. But in the Middle East they were able to eject the Soviets from a position of influence and turn Egypt from a threat into a malleable ally. And their overtures to China exploited the divisions within the communist bloc, helping to set Beijing on an epoch-making new course of economic openness.

The contrast between the foreign policy of the Nixon-Ford years and that of President Jimmy Carter is a stark reminder of how easily foreign policy can founder when there is a failure of strategic thinking. The Iranian revolution of 1979, which took the Carter administration wholly by surprise, was a catastrophe far greater than the loss of South Vietnam.

Remind you of anything? “This is what happens when you get caught by surprise,” an anonymous American official told The New York Times last week. “We’ve had endless strategy sessions for the past two years on Mideast peace, on containing Iran. And how many of them factored in the possibility that Egypt moves from stability to turmoil? None.”
