Can anybody explain how it is possible to gas millions of people without any order, budget or plans?
I am quoting Raul Hilberg, jewish historian:"There was no order, no plan, no budget, nothing. The mass murder of jews took place by an incredible meeting of minds, a consensus of spirits".
The gassing of jews took place thanks to mind reading!
Any psychologist out there can explain how using just facial expressions, you can give the order to kill via gas chambers?
