It's veering a bit off-topic, but there's a fascinating historical debate on the Purges going on since the opening of many Soviet archives post-1990. Some historians (though not all) are moving away from the traditional view of Stalin as mastermind in complete control of the situation, and are putting more emphasis on machinations within the NKVD, which seems to have been the source of a lot more independent activity than we had thought, with Stalin often not appearing to be in the loop. In the strong form of the interpretation that's led some to argue that the purges were primarily a function of the bureaucratic machine, with Stalin mostly riding the wave and trying to stay on top of the chaos. In fact they argue that the traditional view, of Stalin as Machiavellian mastermind, was largely an invention of Stalin himself, who was trying to appear in complete control of the situation. Other interpretations revise the traditional view somewhat less, but most do seem to be putting more emphasis on what was going on in the NKVD.
