To 'all:' thousands of 'ethnic German' refugees were allowed to starve, get diseases, etc. to death after the fall of Germany.
Earlier Germany had destroyed 60% of every standing structure East of their previous national boundaries, with the Soviet Union hit the hardest.
They even murdered millions of people in areas where they were welcomed as liberators!
Definitely the Nazis were not the kind of folks you'd want to welcome to a dinner party.
Sure it was. It was American and British policy to target civilian populations, in both Germany and Japan.
