"It's too soon" < /sarc >
You may never hear the details for the same reason that you may never see a picture of a dead body from the 9-11 attacks.
There would be no debate over "ending the war". The debate would be over "what to hit first".
That's too bad, because that's exactly the kind of debate we need to be having right now. Personally, I think every newspaper in the nation needs to run a front page picture of the bodies of those servicemen, with the caption "THIS IS WHAT WE'RE FIGHTING".
At the Fetterman Massacre in 1866 the slain American soldiers were so mutilated the details were kept closed for about 20 years.
These may be kept closed for a while.
