Republican peculiarities in this political season are so numerous and lurid that insufficient attention is being paid to this: The probable Democratic nominee's principal credential, her service as secretary of state, is undermined by a debacle of remarkable dishonesty.

Hillary Clinton's supposedly supreme presidential qualification is not her public prominence, which is derivative from her marriage, or her unremarkable tenure in a similarly derivative Senate seat. Rather, her supposed credential is her foreign policy mastery. Well.

She cannot be blamed for Vladimir Putin's criminality or, therefore, for the failure of her "reset" with Russia, which was perhaps worth trying. She cannot be blamed for the many defects of the Iran nuclear agreement, which was a presidential obsession. And she cannot be primarily blamed for the calamities of Iraq, Syria and the Islamic State, which were incubated before her State Department tenure. Libya, however, was what is known in tennis as an "unforced error," and Clinton was, with President Barack Obama, its co-author.
