Sorry let me google it for you:

I couldn't find the CIA study though from 2008 but the original Washington Post article is still up: http://www.washingtonpost.com/wp-dyn/content/article/2008/04/30/AR2008043003258.html?nav=rss_world
also I am very sorry to not have made myself clear enough: I do not support these standpoints I do not endorse them, I just tried to explain how they could spring to live in a mind that doesn't have to be infected by an ideology. Also I have never heard of KOPP before this little discussion.

Well if you want to trust such sources, the BND and CIA expect a civil war due to the unsustainably fast demographic change in her country. Further if you compare it to a country where this is more advanced, Sweden, you can tell (not only by the research suggesting it to be a "third world country by 2030") just by looking at it and comparing it to how it was before you have to at least relent a bit in your view. I say this, and correct me if I am strawmanning here, because I believe you believe this is something only a Nazi would say. It is simply a matter of belief for the poster which you can disagree with or not. Not taking any sides or believing in the things I listed up but I just wanted to explain how this viewpoint can come to life.
