See my post above yours.
In any war there are things which have to be kept secret, lest informers and others be compromised.
What is amazingly galling is how the press acted as if it was the final arbiter of everything regarding Iraq and the War on Terror when it was probably privy to only a miniscule fraction of the big picture.
Quite....in WW11 Churchill allowed the city of Coventry to be bombed, although he knew it was going to happen because the German code had been cracked. To evacuate Coventry would have alerted the Germans that their code was compromised.
