Embarassing mistake...

From the Telegraph:

A multi-million pound campaign to boost Germans' low self-confidence has backfired after it emerged that its slogan was first coined by the Nazis.
The £20 million Du Bist Deutschland - You Are Germany - campaign was devised to inspire Germans to stop moaning and do something good for their country.

But a historian from Ludwigshafen has provoked an uproar with his discovery that the same Du Bist Deutschland cry was used at Nazi rallies in the 1930s.
Stefan Mörz uncovered photographs of a 1935 Nazi convention in which soldiers display a banner reading, in gothic script, Denn Du Bist Deutschland (Because You Are Germany). The slogan was topped with the head of Adolf Hitler. Leading Nazis such as Hermann Göring and Joseph Goebbels attended the event.
