On a serious note, it's quite possible that Hitler's personal life did impact upon Germany's history.
Hitler was a personality leader - he captured the public's imagination by tapping into their negativity, and making a section of the population a scapegoat.
His personality was strong - it was like his frame was so powerful, many people went along with it - he had a plan, and people just wanted to go somewhere.
The bitterness and resentment he tapped into - well, like many men, a lot of it perhaps came down to sex and this frustration. If Hitler had been able to connect 'properly' (ok, adequately) in a personal relationship, perhaps he wouldn't have had to have made Germany into a dominant power, out of compensation.
