I was more referring to the end of the war. Even in 1945 when Germany had clearly lost, very large numbers of Germans were prepared to fight to the death to extend Nazi rule by a few days. This included almost the entire civilian population.
So what? In failing to oppose them you - IMHO of course - become guilty of their crimes to almost the same extent as the perpetrators. That is something I wouldn’t be willing to have on my conscience.
That’s the St Petersburg Declaration, which is generally taken to outlaw expanding or explosive bullets fired by a manportable shoulder-fired firearm (that’s what was agreed at the time).
Personally, I think “superfluous injury” is a nonsensical concept in a military weapon - they are specifically designed to kill people, and the way you do that is by causing the maximum possible amount of injury to your target.
Arguably so, but there seems to be nothing in the text to prevent you extending it to a whole besieged country. If you do, then ground defences become relevant - even if they are a hell of a long way away from the target. Aircraft in this case are treated as simply very long range artillery, which to my mind seems appropriate.
Waging agressive war seems to me to be somewhat of an ex post facto crime - ever since the Treaty of Westphalia it had been assumed that a head of state had the right to wage war and that this was somewhere close to an unlimited right (compared to previous moral views). Crimes against humanity are not a postwar invention however - they merely encompass a very large number of individual crimes of murder, which was a crime under the German criminal law prior to the war.
