Right-wing networks in German armed forces

The opposition in Germany demands investigation, following new media reports about right-wing networks in German armed forces (link to ntv news in German). According to a news summary in English by WSWS, testimonies painted a picture “of conspiratorial soldiers, who apparently were even willing to consider targeted killings of political opponents.” This is especially disturbing because Germany also has a history of earlier hidden organisations, linked to German armed forces or secret services, making death lists of political opponents and being covered up by the state. It highlights the general question about the risk of extremism within armed forces and similar organisations.
