I think they did a better job of explaining Joe Smith. *major spoilers*
Last season I was left scratching my head as to how a ruthless Nazi could be a good guy as well.. This time I kind of get it. America lost that war, he was in an American uniform until he looked out the window and saw the big one drop on DC. If he wanted success, or even survival, he was going to become a Nazi. And also his cunning ability to be in the right place at the right time, to think ahead, you could see how he would rise in the ranks so fast. But at heart he's not really a Nazi, what he didn't see coming is that his son really is, and sacrificed himself to be a good one.
