So here's a question from one who believed, only a week ago, that Baghdad might just collapse and that we might wake up one morning to find the Baathist militia and the Iraqi army gone and the Americans walking down Saadun Street with their rifles over their shoulders. If the Iraqis can still hold out against such overwhelming force in Umm Qasr for four days, if they can keep fighting in Basra and Nasiriyah – the latter a city that briefly rose in revolt against Saddam's regime in 1991 – why should Saddam's forces not keep fighting in Baghdad?
