That doesn't mean that not mitigating when you sell your house is homocidal. (I worked as a mitigator for a while) Will we mitigate the radiological and chemical problems we are causing in Iraq? Unlikely. (and there ARE problems, and it IS bad for you).
Is it genocide? Is using DU like sowing U235 in the fields? Of course not. I wouldn't eat any food grown in a field that was the site of a tank battle using DU rounds, though. I would prefer not to live in a neighborhood that's been contaminated, either. But silly me. I wouldn't live next to a city dump or a Union Carbide plant, either.
