Seconded that Genstabler and Mal Drop. Unlike anybody on the Daily Mail it appears, and unfortunately a lot of those who have posted on here, I actually listened to the Archbishop, and noted that he carefully did not apologise for the bombing, and has subsequently made that clear in the light of ill-judged criticism of his words. Certainly reference to it as a horrific event is not a statement that can be argued with, any more than the description of hundreds of other incidents during the war. War is horrific, acknowledgement of the fact does not involve ascribing blame or apologising.
Personally I think it is nonsense to apologise for events for which you were not responsible. Since nobody is left alive who was in a position of responsibiilty in any of the participating nations, nobody can be expected to take it upon themselves to apologise for Dresden, Coventry, Hiroshima, the Burma Railway or anything else.
