CrossTalk on 'Gorbyology'

On this edition of Peter Lavelle's CrossTalk: As Gorbachev celebrates his 80th birthday, what does his name mean to the world today? How will history judge him? Why is he loved in the West and criticized in his native country? Is it too early to draw conclusions? And what makes him a peacemaker in the eyes of many nations? CrossTalking with Stephen Cohen, Geoffrey Hosking and Vlad Sobell.
