Although the ICC is increasingly important as an arbiter of legally accepatable behavior by heads of state, recent events suggest that it may be a check against (or at least a nagging worry for) warlords looking to rise to power. In the good old days, you were only scrutinized after you seized power; now, what you do on your way up is being noted, catalogued, and filed away for a court room down the line. Step by bloody step, the road to dictatorship just got a little less lonely. You might imagine a manacled tyrant saying, after enjoying only a brief tenure as president, 'I had no idea everything I did was forever!'
If it truly is, then that's good news for the rest of us.
