Another idea:

The colors of the German flag are black, yellow, and red. If yellow translates to gold, it could be about the darkness of Germany's past. You know, the nazi regime, et cetera. And of course, ignorant non-Germans automatically think of nazi when they hear "Germany", so the country is still suffering from its past.

"A world of ruin all in vain"... obvious, holocaust and whatnot. "All in vain" meaning how nothing but, well, bad-ness came from it. Yeah.

"It's in the open but it doesn't get stolen" This line reminds me of a story about Vlad the Impaler; supposedly he left a golden cup or something out in the centre of the town square, by a fountain or something, and nobody stole it for fear of being, well, impaled. And I know that's a completely different, well, region of the earth, but Vlad was a dictator and so was Hitler. Just a thought.

"It is as black as Malevich's square" Kazimir Malevich is a russian painter who painted "Black Square" (which is just what it sounds like; a black square). So that's probably just a weird, abstract simile.

That's... all I really know. Anyway. That's all.
