Re: Deutschland über alles. I think we have heard that before!
No, it has a completely differnet meaning.
"uber alles" is used for everything in German, like "for the world" in English.
For example, if pizza is your favorite food, you would say "pizza for the world" in English and "Pizza über alles" in German. It just means "there is nothing better than pizza"- It has no connotation of ruling oder domination or anything. It also does not mean that you put pizza above something, it means that you find out that it is above something.
