I read this book back in one of the IR undergraduate classes. It's been a long time. I re-read the book again (10 years later), I must admit, I now see the world differently and I was not able to fully understand these big ideas rather than passing the class. Reading it as pleasure now, Mannn... this book is well written with full facts about what theories and model for keeping the world running and the reality of the geopolitical factors and personalities of world leaders that can influence everyone of our lives.
I will never stop learning.
