Since the 1960s, we have seen the failure of the melting pot ideology. This ideology suggested that different historical, cultural and socioeconomic backgrounds could be subordinated to a larger ideology or social amalgam which is "America." This concept obviously did not work, because paradoxically America encourages a politics of contestation.
All the words that George Bush used in public during the early stages of the crisis - "wanted, dead or alive," "a crusade," etc. - suggest not so much an orderly and considered progress towards bringing the man to justice according to international norms, but rather something apocalyptic, something of the order of the criminal atrocity itself. That will make matters a lot, lot worse, because there are always consequences.
Uninformed and yet open to appeals for justice as they are, Americans are capable of reacting as they did to the ANC campaign against apartheid, which finally changed the balance of forces inside South Africa.
