People were killed. Some jewish slums were liquidated, especially nearing the end of the war.
A few higher ups were involved, however on numerous occassions people who were close to Adolf noted, that he took news of mass killings poorly.
In one case he sent a very angry message to an officer, stating his orders had been far in excess to what his command allowed, and that he should cease such actions immediately.
After reading further information, as well as diaries and logs written by people that were close to Hitler throughout, I believe a splinter group may have begun extermination, especially when some belived that Germany was doomed to lose the war.
Adolf with his failing physical and mental health, was obviously oblivious or uncaring to the circumstances, especially with more pressing matter at hand.
Jews may have been killed in large numbers, however the number have no doubtedly been inflated.
This is especially obvious when comparing to prior Jewish publications, and their obsession with the 6 million number.
I believe one of their religious scriptures mentions 6 million will die for israel to be born (sorry for basterdizing the quote)
What makes it more obvious that something is amiss, is the intentional ignorance regarding soviet war crimes / the communist death count.
Of course Germany had to be demonizes to justify such a waste of young mens lives, the enemy is always the devil.
History is written by the victors. When the world turns against you, what chance is their for truth in the end?
