Actually, it is far from any such rather quaint suggestions. What precisely is the 'pride of man of civilians'?
I am not justifying nor supporting the Holocaust here, and the very imputation of such vile ad hominem attacks is both uncalled for, and evidence of the bankruptcy of the case you put forth; it is yet another example of fallacious over use of emotive empty rhetoric in the place of any proof or argument. My grandfathers and relatives fought against the perpetrators of the Holocaust and war crimes, and were on the side that beat them and bought them to justice. I find such drivel repugnant, unnecessary and the lowest form of insult. I will concentrate on your points, limited as they are.
Other discussions related to fictional matters are most irrelevant, and have no bearing on this REAL issue. The issue is what is being discussed here in regards to the deployment of atomic bombs by the United States against Japan.
Undefended cities is an interesting issue. Virtually no cities can be said to be undefended in terms of AA defence, civil defence and military installations. Hiroshima, Nagasaki, Dresden, Berlin, Hamburg, Cologne - none of these were undefended.
It is a jump from the Hague conventions of pre-WW2 to what was a warcrime; war crimes are those which were codified by the judgement at Nuremburg. No one was charged with the bombing of civilians, nor with strategic bombing. If we apply all parts of the Hague and subsequent conventions, then there are going to be a lot of war criminals.
The articles in both 1899 and 1907 regarding the bombardment of undefended 'towns, villages, habitations or buildings' would definitely make war criminals of most involved on all sides, even if we limit it to its sense of artillery. By extension, a shell from Warspite that accidentally hit a farmhouse in Normandy was a warcrime.
I refer to a 1998 article on the History of Air Warfare:
"In examining these events in the light of international humanitarian law, it should be borne in mind that during the Second World War there was no agreement, treaty, convention or any other instrument governing the protection of the civilian population or civilian property, as the Conventions then in force dealt only with the protection of the wounded and the sick on the battlefield and in naval warfare, hospital ships, the laws and customs of war and the protection of prisoners war" 'The Law of Air Warfare', Javier Guisández Gómez, 1998 International Review of the Red Cross no 323,
It is only in 1949, after the fact, do we get to the meat dealing with the protection of civilians. If we take a position that Nuremberg was victors justice and ex post facto, then this position applies to all parties, not simply the Germans.
There is a more reputable case to make in favour of applying the label of war criminal to all those involved in the U-Boat offensive than the RAF and USAAF Bomber Offensive, let alone the civilian leadership in both countries, and by extension the Empire.
It is not a matter of attacking civilians. It is a matter of destroying infrastructure, factories, machine tools and seriously impeding the enemy war effort. It was simply impossible to delineate the difference between industrial and civilian targets using the technology of the time even in the case of Germany, and certainly so over Japan, given its particular circumstances. This is something you conveniently fail to address in your eagerness to cast mud.
What is the difference between an 'attack on industrial targets with collateral damage' and an undefended city?
The bombing of Tokyo was certainly not intended as a terror bombing, but as a strategic attack on the industry, morale and war making potential of the Japanese Empire. Conventional iron bombs would not have been at all effective, given the dispersal of industry. Account, if you can, for the characterization of its only purpose being as a terror bombing. Provide evidence from the USAAF and the Strategic Bombing Survey.
As previously pointed out, and conveniently ignored, the purpose of deploying the atomic bomb over Hiroshima and Nagasaki was that these were relatively untouched military targets; that the impact of the bomb was to act as the necessary shock to force Japan into ending the war; that the bombs regardless of their impact were to also destroy a portion of the war making potential of the Empire of Japan; that a quick end to the war was required.
It is not a matter of attacking civilians. They are not a factor. They cannot be effectively separated from targets in a total war using the methods available in the 1940s. To pretend otherwise is to avoid the facts.
