Almost certainly the best-known German language song outside of German, this little warning of the apocalypse was a big hit in the 1980s.  Yes, people in the US were singing along to their death from nuclear attack. 
And who would blame them??  This song is damned catchy.
In a bit of an oddity, an English language version of the song - slightly changing the narrative to be even a little darker - was released  THIS VERSION DID NOT CHART, meaning the US audience preferred not to know what they were singing about, I guess.
