So are you saying there are no aggressors in war situations? For example that Germany & Japan were not aggressors who had to be resisted and ultimately defeated? Of course they were and it has taught us the lesson that is repeated time& again throughout history, that nations need to arm themselves witb weapons to deter aggression. Messrs Topf & Sons however have no excuse for knowingly building ovens for the disposal of the victims of genocide. Totally different argument.
