I see eggs, not chickens
Not time to start counting, we don't know yet if the marshes will return. And if they do, it'll be up to the Iraqis, primarily, to decide that issue, and they should get primary credit.
Bush should get some credit though, I'll concede that. It doesn't compare to Gore's work on the Kyoto Protocol, Clinton's on land set asides, Bush I on no net loss of wetlands, not to CERCLA/Superfund during Reagan years, Alaska preservation under Carter, and most importantly all the environmental laws that Nixon signed. Baby Bush might outdo Ford, maybe.
