While I would never take ANSWER's word if they told me it was day or night, those appear to be two different photos. The soldiers have different poses in each picture and it appears that the soldier is pointing us weapon only in the general direction of the girl, most likely well at the men you see in the second photo. If anything they cropped the Iraqis near the red car out.
Besides, there is literally NOTHING you can say to them that would change their minds. They hate America and they especially hate soldiers in Iraq. Don't waste your breath or time.
What you say is correct, but.... In the larger photograph it is obvious that the little girl is curious, but she does not feel any appear danger. If she were afraid she could duck back behind the opening in wall. The smaller photograph does convey a sense of danger, the soldier seems to be pointing his weapon in her direction and she does appear closer.
