Nope. The song is strongly associated with the Nazi regime, notwithstanding its continued use by the BRD. Wikipedia entry on Deutschlandlied:
During the Nazi era only the first stanza was used, followed by the SA song "Horst-Wessel-Lied".[10] It was played at occasions of great national significance such as the opening of the 1936 Summer Olympics in Berlin when Hitler and his entourage, along with Olympic officials, walked into the stadium amid a chorus of three thousand Germans singing "Deutschland, Deutschland über alles". In this way, the first verse became closely identified with the Nazi regime.
As for :which: Reich is referenced? Are you joking? Any references to a German Reich clearly associate with the Third Reich.
All this ahistorical apologism is absurd. Bye!
