John F. Kennedy said this quote

“ After visiting these two places (Berchtesgaden and the Eagle's lair on Obersalzberg) you can easily see how that within a few years Hitler will emerge from the hatred that surrounds him now as one of the most significant figures who ever lived. He had boundless ambition for his country, which rendered him a menace to the peace of the world, but he had a mystery about him in the way that he lived and in the manner of his death that will live and grow after him. He had in him the stuff of which legends are made. ”
