Just finished reading
William Taubman's Gorbachev. It's a good book, as a winner of the Pulitzer should be. The focus is, of course, on political history. I don't remember any great surprises that weren't fairly clear in the newspapers of the time, except for the closeness of Mikhail and his wife and family. Yes, he faced a lot of opposition over the years, from both liberals who wanted to go further and differently and conservatives who didn't want to change the system in which they had prospered. Yes, he maneuvered back and forth first to rise to power and then to maintain his power while trying to move the country towards his goals, which turned out to be a liberal social democracy (though that seems to have been a post facto realization.
Taubman writes well, seems to have interviewed those Soviet figures still living, and doesn't force his conclusions. He reports differing assessments from friends and foes, including a number of people who began as allies and ended disappointed and disaffected.
I, as I suspect most American readers would be, was most interested in his foreign policy and dealings with other world leaders. He got on well with his counterparts, from Thatcher and Reagan, Mitterand and Kohl, to Bush. The glimpse of Thatcher through Soviet eyes was particularly interesting. Taubman's assessment of the Bush approach to Gorbachev is mixed: Bush's personality and upbringing meant he eased Gorbachev's way, but it also meant he perhaps missed a chance to push events in a better direction, one which might have averted our current state of hostility between Russia and the U.S., but who knows?
