[I]t's certainly true that closed, secretive networks become less effective--but that doesn't mean they become less effective at the things we dislike them doing. Stalin remained exceptionally good at purges and liquidations all through World War II, and that didn't stop him from helping to win the war, and dominating half of Europe. It's just that it took more dead Russian boys to do it, because being secretive and purge-oriented kind of hampered the efficiency of the economy, leaving them a little short of key items like guns. But since Stalin was running a super-secretive, centrally controlled regime, that insight didn't really matter.
