Christopher C. Hull reflects on whether it is better for a prince to be feared or loved. He notes that North Korea did a 180 degree turn a few days after the fall of Baghdad, and reflects on this by talking about Mansfields grading system: "Feared or loved, which is better? As Prof. Harvey C. (minus) Mansfield of Harvard teaches, the challenge is that if a professor gives out As, then students will love him - but if he then gives a student a C, that student will hate him. If, however, the professor gives out Cs, then students will fear him, and if he gives out more Cs, students will simply continue to fear him. But any As he scatters about will cause those students to fear AND love him. (Note: He wasnt kidding.)" The rest is worth reading, too.
