There's nothing like grading final exams to make me feel like a failure as a teacher.
The question was about the Pentagon Papers case (a case where the NY Times and Washington Post published a stolen Pentagon report revealing the military's conclusion that the Vietnam War was unwinnable).
The answer: "The Pentagon Papers case was a case about Richard Nixon stealing documents from the Pentagon to get reelected."
Sigh. Sometimes it feels hopeless. And that was from a front row student, not even one of the backbenchers.
