Geez, you have forgotten it!
This was important back in the 90s during the Clinton era:
In his first year (1965) in the School of Foreign Service at Georgetown, Bill Clinton took Quigley’s course, receiving a ‘B’ as his final grade in both semesters (an excellent grade in a course where nearly half the students received D or lower). In 1991, Clinton named Quigley as an important influence on his aspirations and political philosophy, when Clinton launched his presidential campaign in a speech at Georgetown.
I was a young-in in the Clinton era.
I have never heard of this book until now.
I will look it up.
