Pr00ne,
There was also already the Air Crew Europe medal, which rendered a dedicated Bomber Command medal superfluous (and potentially divisive). Perhaps a bar or a rosette (like the 8th Army bar on the Africa Star or the Battle of Britain addition to whichever medal) would have been appropriate.
Maple 01,
You're absolutely right. The record of the Merlin Halifax (in service for a year before the Lanc arrived) was poor, and drags down overall statistics. Harris absolutely based his opinions on these early aircraft, and then entirely failed to revise his views when the III (and the even better VI and VII) came along. But that was perhaps because all that mattered to him was the tonnage of bombs delivered per £ spent on aircraft manufactured, regardless of the cost to his own aircrew.
Blacksheep,
The morality of the nuclear deterrent is a complex subject. One could argue about it all day, I suspect, though I always believed in it during the Cold War (as a necessary and proportionate evil) and incline to the view that history showed that there was no alternative and that it worked. Some would suggest that because it was intended as a deterrent (rather than to be used) it was the most moral 'weapon' of all. Others might say that the massive civilian deaths it would have caused would at least have been collateral to the main purpose of the attack.....
But the unique feature of Harris' strategy in WWII was that it was not just indiscriminate (like the appalling and equally immoral German V-weapons) but was specifically intended and then carefully refined to maximise civilian casualties. And there were alternatives available, that would have worked better.
