Iraq: seems short-sighted to me. We don't tend to judge past civilisations based on one war.
SUVs: maybe, but I would say our continued reliance on oil in general rather than SUVs in particular.
Bullying: could be.
Parasites on the welfare system: not convinced. The fact we have a welfare system will be judged favourably I expect.
Predatory banking practices: pass, not sure.
It's hard to imagine what things it will be--their values may be very different from ours. I'd say oil reliance, over population, the gulf between the rich and the impoverished, but these things are all too obvious. I suspect we'd be surprised by what we're judged badly for.
