John Kerry's Mark on History.

It's a tiny one:

"Nobody puts the SoS in Secretary of State quite like John Kerry, who has overseen the rout of American influence and prestige in every corner of the globe, managing the neat trick of making Hillary Clinton look relatively consequential, or at least harmless. Kerry has finally been given the recognition he deserves by foreign policy scholars, who named him the least effective SecState of the past 50 years."

Not surprisingly, Henry Kissinger was ranked #1.
