After WWII, a US Navy officer used Hitler’s personal stationery to write this letter to his son. The full letter, which was written by future CIA director Richard helms, reads: 

“Dear Dennis, 

The man who might have written on this card once controlled Europe– three short years ago when you were born. Today he is dead, his memory despised, his country in ruins. He had a thirst for power, a low opinion of man as an individual, and a fear of intellectual honesty. He was a force for evil in the world. His passing, his defeat – a boon for mankind. But thousands died that it might be so. The price for ridding society of bad is always high. 

Love, Daddy.“
