The Munich Oktoberfest Bombing, 40 years on.

Forty years ago today - on September 26, 1980 - neo-Nazis detonated a nail bomb in a bin at the entrance to the Munich Oktoberfest, killing twelve people and injuring 221 more, many of them seriously. It remains - alongside the 1972 Munich Olympics attack - the deadliest terror attack in modern German history, and is the most deadly by the far-right since 1945. Yet the investigation by the Bavarian State Criminal Police remains one of the most serious failures by German investigative authorities.

The man still officially considered to be the sole perpetrator, Gundolf Köhler, was killed in the blast. He was known to be involved in neo-fascist circles, including the Wehrsportgruppe Hoffmann (“Hoffmann Military Sports Group”) - a neo-Nazi militia organisation which was banned in Germany the same year. He also had a portrait of Hitler hanging over his bed. Germany had seen numerous far-right attacks in the preceding years, and in 1980 itself.

Nonetheless, Bavarian police quickly concluded that the attack was not politically motivated, and closed their investigations in 1982. They also concluded that Köhler had acted alone, despite convincing indications of others being involved in the attack. This included several witnesses testifying to having seen Köhler arguing with two men in German army parkas shortly before the explosion. Confessions by two imprisoned fascist activists about military training and weapons dumps in the forest were not followed up either.

Fortunately, demands to re-open the investigation continued. In 2009, inquiries by the Greens revealed that the domestic intelligence agencies in three German states (Bavaria, Baden-Württemberg and Hesse) had been closely monitoring the neo-Nazi militia Wehrsportgruppe Hoffmann only hours before the bombing. In 2010, a request from the victims' lawyers for access to the DNA evidence revealed that all of the evidence had been destroyed in 1997 - much of it never having been fully tested - including a severed hand that was never identified.

In 2011, Der Spiegel magazine reported on some 46,000 pages of previously unpublished investigation files, which revealed that authorities were already aware of Köhler at the time of the attack, and considered him to be “firmly rooted in a milieu of militant neo-Nazis” which also “maintained intensive contacts with CSU functionaries”. (The CSU - Christian Social Union - is the Bavarian sister party to German Chancellor Angela Merkel’s Christian Democratic Union and has governed Bavaria every year bar three since 1946).

Der Spiegel reported that the files also showed Köhler was motivated by a desire to help the conservative CSU’s candidate for Chancellor, Franz Josef Strauss, win the October 1980 federal elections by carrying out a false-flag attack that could be blamed on the left. Köhler was unsuccessful, both in laying the blame on the left, and in electing Strauss. Although the CDU/CSU remained the largest party in the German Bundestag, the social democrat Helmut Schmidt remained Chancellor.

Following years of campaigning by relatives, victim representatives, lawyers, trade unions, journalists and politicians, the investigation was finally re-opened in 2014. The German government and intelligence services continued to be difficult and obstructionist. They refused to admit that there were intelligence informants in the Wehrsportgruppe Hoffmann (a fact later established), leading Die Linke and the Greens to lodge a complaint with the German Constitutional Court.

In April 2016, in response to enquiries by the Die Linke MP Martina Renner, the Federal Government also revealed that only the Federal Intelligence Service The “Bundesnachrichtendienst”) had handed over its files on the case, while the Bundesamt für Verfassungsschutz (“Federal Office for Protection of the Constitution” - BfV) had not done so - despite holding the majority of the relevant material.

The investigation was closed again in July this year, but not before it was determined that Köhler had been, in fact, motivated by far-right extremism and a desire to build “a Führer-state based on the model of National Socialism”. It was also found that while there “were not sufficient indications” to show that others were involved in the bombing, such a scenario “cannot be ruled out.”

Forty years after this terrible atrocity, the victims are only just now receiving proper compensation - and this only after years of campaigning. Meanwhile, the German state is reeling from revelations of extensive far-right activities in the army, police and intelligence services, death threats against politicians, and a rising rate of neo-fascist violence and killings across the country.

Unfortunately, the Oktoberfest bombing - including its botched investigation - looks less like an exception, and more like one example among many more of neo-Nazi violence tolerated and covered-up by elements of the state apparatus. This was neither the first nor the last time that German authorities obstructed and obscured investigations into right-wing terrorist attacks. At best, the investigation was an incompetent farce - more likely, there was deliberate obstruction and obfuscation, as there was in the National Socialist Underground (NSU) terror case.

The bitter reality today is that the danger of right-wing terror is an immediate threat once again, but the German state services remain unreformed, and are demonstratively compromised. The fight for democracy remains a battle of remembering against forgetting, and it is vital that decades of wilful ignorance - and worse - by German authorities of the continuing Nazi threat is exposed and undone.
