In this provocative book, Parag Khanna turns on its head much of the assumed reality of 21st century power. He suggests that in almost every way modern life is now a retreat to medievalism. Governments no longer have a monopoly on high policy and running countries; NGOs are increasingly more effective; corporations are the new glue. He identifies a new technologically enabled ‘mega-diplomacy’ operating across almost every community which is creating new unity and marginalizing ideology. Rather than being perfect, it is a new form of accommodation. The concern in this medievalist world is: Who now has the responsibility? Parag Khanna goes a long way to suggesting answers that many will find uncomfortable.
