First things first, facts:

I imagine the NSDAP was extremely pro unification with Prussia, no?

The NSDAP was founded in 1920, DAP was the predecessor but also only founded it 1919. Prussia become a part of a unified Germany in 1871. There was no opinion to be had on Prussia joining Germany because it was already party of a Germany state.

Now for the rephrasing:

Let me try to explain it. Are you familiar with Duty to Rescue laws? In Germany and many other countries you have a legal obligation to help a person in need unless your own life be in jepeordy by helping, this means that if you don't you've commited a crime. Essentially this idea that I've only heard other Germans espouse is a Duty to Rescue for an entire nation. Now we have in our constitution an article that grants a Right of Revolution:

Article 20 (Basic principles of state order, right to resist).

(1) The Federal Republic of Germany is a democratic and social Federal state.

(2) All state authority emanates from the people. It is exercised by the people by means of elections and voting and by separate legislative, executive and judicial organs.

(3) Legislation is subject to the constitutional order; the executive and the judiciary are bound by the law.

(4) All Germans shall have the right to resist any person seeking to abolish this constitutional order, should no other remedy be possible.

Essentially, morally and ethically those two ideas have fused and have become a duty to overthrow an non-democratic government, not in any legal sense of the matter, but are held as simple truths in my generation on Germans. The ethical stance is projected by some on the generation that actually lived through the war as early as 1968 when the 68ers (our very own, a lot less drugy, hippies) asked their parents three very important questions: "What happend?", "Why did it happen?" and "Why didn't you do anything to stop it?"

For years I though I was alone in this rather radical stance, until once in school in an ethics course one of our teachers held an anonymous poll of the present 22 students. The question was: "What would you do if Nazis or a nazi-esque movement took over Germany again? For the purposes all legal ways have yielded no results." The answers were 1. Stay 2. a) leave the country b) leave the country and help fight against them by working for other countries (propaganda, espionage) 3. Stay and peacefully protest even under the thread of bodily harm and 4) Stay and fight a) by sabotage b) armed conflict c) any means necessary (including harming cilivians and acts of terrorism).

The results were equally disturbing and uplifting at the same time. 1. got 0. 2. got 7 ( a) 3; b) 4). 3. got 7 and 4. got 8 (a) 1; b) 5; c) 2). Even if you account for that class being very well educated and assume that the other 2/3 of my generation would blindly support such a regime (which can't be true either), that's millions of people young millienias who'd rather blow their country up until nothing stands anymore than let fascists rule. So the teacher asked why so many were willing to fight (apperantly his generation wasn't that willing) and pretty much every single answer he got, from every single one of those groups came down to a duty towards the people of other countries and to the country. One girl even said that she saw it as an act of treason to the people to support a dictatorship. I learned that day that I'm not that radical when put in context of my generation.

Another few years later I learned that this isn't at all how other nations thought of it. Talking to Americans and Brits they spoke of the Germans who resisted as being heroes, which led to a few weird arguments and equal non-understanding of my generations stance. It's only the past year or so that I truely have understood what it means: my generation of Germans have come to believe that your right to life and not be harmed ends when the right to life of thousand or even millions of others are in jeopardy; at which point you have aa duty to sacrifice everything and help anyway you can to stop it.

This was quite important to me because I had previously, thanks to being taught history, lost all pride of my country in fact I had started not to feel German at all and now I felt part of a New Germany that is very different from the Germany from 50 or 100 years ago.

If you project this idea back into the era of the war, it is of course highly unfair. But we can assume that an incredibly small number of those who died or otherwise had their rights violated were "truely innocent" because they had resisted - ergo they were guilty (except of course for the children) of helping by letting it happen. So that the outrage can be countered with "Karma's a bitch, isn't it?".

Now, of course what happend wasn't right or just, but I fail to have sympathy whenever it comes down to it.
