Germany has fought a hard battle to recover from its Nazi past. But in the last several months, the country has seen a rise in brutal neo-nazi crimes.  German police discovered a neo-Nazi terror cell in Zwickau that had been operating for the last decade. They are responsible for the murders of at least ten people.  Earlier this month, the Thor Steinar clothing brand, popular among neo-Nazis, opened up a t-shirt shop which it named Brevik,  a play on the name of the Norwegian mass murderer Anders Breivik, a man who killed 77 people last year.
