First of all, there is a question of manpower - I would not be surprised that the population of Russia now will be around 1/3 of Warsaw Pact countries population.
Second, since 1979 Russia had a number of pretty unsuccessful and bloody wars: Afgan War, First Chechen War, and Second Chechen War (which is still going on and on). Russian society had openly tired of wars, even Second Chechen War which was widely supported by society at the beginning is running out of steam.
Third, if one would compare disarray of armed forces, Russia's problems are the biggest. So, it is not surprising to see the change of stance on the right to use nukes first. Russia now assumes the possibility of using nukes first - it is a clear defensive stance of the country which is thinking mostly about its own defences and their cost(I can expand on it, if it is not evident).
Fourth, Gorbachev is a moron, the author's accolades to him is yet another evidence that the author is moron too.

Sounds desperate. Also it sounds anything but defensive.
