Officials at Germany’s Stasi archive have agreed to release some information showing West Germany’s secret service employed former Nazi criminals. But some key data remains under wraps. It’s one of the country’s worst-kept secrets. Yet questions still surround the presence of former Nazis and war criminals in West Germany’s police, secret service (BND) and politics. Who were those people, what positions did they hold in Nazi Germany and later in post-war West Germany? East Germany’s secret police collected information to blackmail or discredit its capitalist neighborCrucial information about the BND’s past has long been hidden in the Stasi files – the vast archive of information meticulously gathered by former Communist East Germany’s secret police, the Stasi. The aim was to either blackmail Western agents or to discredit its capitalist neighbor to the west. After reunification some of those documents were made available, but parts of the archives remained locked away for reasons of data privacy.
