I don't think Moore is trying to draw parallels between the American presence in Iraq and Cylons, but he is asking the audience to ask hard questions "What would we do in such a situation?" Would we resort to measures that we now find deplorable? I think it's clear Colonel Tigh is not the moral voice on the show. There really isn't one, but especially not Tigh who has repeatedly made bad calls throughout the course of the show. But you look at where Tigh stands now, and you understand how he got there, even though he's advocating things we find deplorable. That's what's great about this show. Nothing about it is so simple that you should say "Oh, they are criticizing the war in Iraq". No, just like they have done since the beginning, they are putting their characters in complex moral and political scenarios, where they need to make very difficult decisions, and they are asking the audience to shift their perspective in a way many of them are probably not comfortable with. That's why it's not that surprising that some folks have taken a really simplistic stance that the show is just criticizing the occupation in Iraq it's because the show is making them ask questions they are not willing to ask themselves, and they are lashing out.
