Answer:
American citizens were aware that Hitler was a man of passion, meaning they also knew of his book, Mein Kampf (My Struggles). They didn't think very high of him. Even as Hitler rose to power in his own government, the other officials saw his thirst for power. Americans thought German could control him, and so did those of high political status. But, as chaos began erupting, Hitler appointed himself to be Chancellor of Germany, a role he invented as he destroyed the role of president once the president died. Americans still didn't see him as a threat. Even when newspapers discussing concentration camps started slowly seeping out, Americans were in complete disbelief. American soldiers, too! But once American soldiers stumbled upon concentrations camps, they were locked in shock as they realized the dark fables published were true.
