The world is full of people who say “I would have refused, and taken the bullet to the head” There are very few who would actually do that.
IMO, the war crimes tribunals are an abomination. War is hell, Americans did much the same to the Native Americans. Churchill and the British military did this to the families of the Boers who were fighting to repel the British. So Churchill is the first example of a leader who preceded Hitler, doing the same things. For that matter, they starved the Irish too.
The war is over, God ultimately has final judgment on what happened.
