The Obama administration has fought al Qaeda and its allies ferociously. But it has been disciplined about the use of force, and understandably so. An America that exaggerates threats, overreacts to problems and intervenes unilaterally would produce the very damage to its credibility that people are worried about. After all, just six years ago, the United States’ closest allies were distancing themselves from Washington because it was seen as aggressive, expansionist and militaristic. Iran was popular in the Middle East in 2006 because it was seen as standing up to an imperialist America that had invaded and occupied an Arab country. And nothing damaged U.S. credibility in the Cold War more than Vietnam.
