No, bomb military targets. Oh, wait, that's what we're doing. Of course, it would be more moral to bomb military targets in a rich country rather than in a poor country, but they haven't hidden any bunkers in Manhatten. Oh, wait, but they did bomb Manhatten.
You're going to need to find yourself another straw man with whom to argue. I did not say bombing rich countries is any more moral than bombing poor countries - it obviously isn't. However, the poverty of the Afghans is absolutely relevant because it means that attacks on them are all the more devastating. Think freezing or starving to death whilst fleeing a war zone.
