The assault on the U.S. consulate in Benghazi, Libya promises to play a big role in Monday’s debate between President Barack Obama and former Governor Mitt Romney. But don’t cringe: For all the silly gotcha moments about who cried “terror” and when, the Benghazi attack provides a chance for both candidates to address major concerns about their approaches to a chaotic world. The first round of congressional hearings on the Benghazi assault have come and gone. But they didn’t focus on the crucial question of the strategic implications of the assault. Does it mean the U.S. needs to involve itself deeper in the Arab Spring; pick favorites within the uprisings; or stand back as the the upheaval proceeds? Both candidates have said a lot about the incident and practically nothing about arguably the most important questions it raised.
