I asked, what aid can anyone give? Nothing will help the corpses, and the good folks know that. In any case, they aren't going to pour out of their homes to confront an angry mob. Nobody does that, anywhere.
One cannot reliably infer from the lack of aid that there is no pro-American sentiment even in Fallujah in the notorious "Sunni Triangle," the worst remaining center of resistance. My (inexpert) understanding is that most of the country is Shiite, hospitable and remarkably safe.
Btw, the TV news I was watching gave the population of Fallujah at 230,000, not a million -- not that its size makes much difference. The anchor also admitted that many in Fallujah were disgusted by the spectacle -- as well they should have been, for it was barbaric and shamed their city.
