As Bill Clinton might have said, it depends on what the meaning of good is. Certainly, even many of her most ardent defenders recognize Hillary Clinton had no signal accomplishment at the State Department to her name, no indelible peace sealed with her handshake, no war averted, no nuclear crisis defused. There are few Eric Schmidts out there still willing to make the case for her as an enormously consequential figure in the history of Foggy Bottom.

Where the debate tends to rage is over why that is so, especially now that Kerry is taking on diplomatic challenges that Clinton either couldn’t or wouldn’t—from negotiating a potentially historic nuclear deal with Iran to seeking a revived Mideast peace process—and political rivals in both parties return to thinking of Clinton in the hypercharged American political context and not so much as the tireless, Blackberry-wielding face of global glad-handing.

I asked an array of smart foreign policy thinkers in both parties to weigh in, and they pretty much all agreed that Clinton was both more cautious and more constrained than Kerry. Their argument is over whether and to what extent that was a consequence of Clinton herself, the limits placed on her by a suspicious and eager-to-make-its-mark first-term White House, or simply it being a very different moment in world politics.
