So here's a question from one who believed, only a week ago, that Baghdad might just collapse, 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 Nassariyeh - the latter a city which briefly rose in successful revolt against Saddam in 1991 - why should Saddam's forces not keep fighting in Baghdad?
