On Falluja: From The Guardian:

Assaults on cities serve symbolic purposes: they are set showpieces to demonstrate resolve and inculcate fear. To that end, large numbers of casualties are required: they are not an accidental byproduct but the aim. That was the thinking behind 9/11, and Falluja risks becoming a horrible mirror-image of that atrocity. Only by the shores of that dusty lake in Dreamland would it be possible to believe that the ruination of this city will do anything to enhance the legitimacy of the US occupation and of the Iraqi government it appointed.

From Tony Kevin of the Sydney Morning Herald:

This attack will also violate the rules of war and the Geneva conventions in having grossly indiscriminate effects on civilians and civilian homes and infrastructure. America's largely untrained in battle but over-armed forces will start their attack "humanely", but as they inevitably take numbers of lethal casualties, their tactics will quickly escalate to indiscriminate bombing and shelling of the city using their WMD armories.

Eventually, the attackers will flatten the city and kill everyone that still resists in it. Falluja will be the Iraqi people's Masada, and it will sow seeds of deep anti-Western hatred in the Middle East for decades to come.

And Xinhuanet reports that 35 US soldiers have been kidnapped in the city.
