My own take is that this approaches the siege of Hue City when 5th Marines took the Citadel. Victor Davis Hanson does a remarkable telling of that story in Carnage and Culture.
I wish I could believe your explanation for Matthew's comments..that he was only referring to tactical/military issues. But I heard him and its not the first time he has voiced that type of sentinment. No one has called him on it..but someone should. He asked directly if the "people of falluja" were manning their posts like at stalingard." A transcript I am sure is available and I predict is even more damming that what I have said. I say "damming" if you believe that it is outrageous for him to make that historical analogy putting us with the Nazi's and the terrorist with the brave defenders of Stalingard.
