In his first act as prime minister on Monday, Alexis Tsipras visited the war memorial in Kaisariani where 200 Greek resistance fighters were slaughtered by the Nazis in 1944. The move did not go unnoticed in Berlin. Then came the announcement that radical academic Yanis Varoufakis, who once likened German austerity policies to "fiscal waterboarding", would be taking over as Greek finance minister.
