I guess George Bush's vision of 'Democracy on the March' was right. Once the idea of mass assembly to protest dictators takes hold, given the media spotlight, it's hard to put that genie back in the bottle.
By the way, let's not forget that this entire round of events was triggered (not by George Bush - I was kidding) by one Tunisian who reached the point where he was willing to self-immolate, to prove that he was serious. THAT was the spark, not the Iraq invasion (despite what certain pundits will inevitably assert).
