Hey with that Speer question on positive impact you can actually spend half arguing positive and half negative. My thesis for that question is that the extent to which Speer's contribution can be viewed as positive is dependent on the context in which it is viewed. For example, on the one hand, his work in Anti-Semitic policies were negative as they were inhumane in their treatment of the Jewish people (according to historians today and influence by today's context's view of the Nazi party as immoral). However, in the context of the Nazi party, this was a positive impact as the Nazis preached anti-Semitism and the sacrifice of the Jews for the good of Aryan Germany. You can argue something similar for his role in Propaganda and Armaments Minister and of course Good Nazi and now, with more evidence, Bad Nazi. So in effect, now, the Nazi Party is associated with being inhumane and evil and hence, Speer's work, being for the Nazi Party is seen in a similar light. Yet, in the context of Nazi Germany, what he did was positive. And as Susie said you structure it PROPAGANDA - Positive in this context, negative in this context. ARMAMENTS - Positive in this context, negative in this context etc. etc.
