I have no idea who is behind the the "news" magazine and Web site Hintergrund (in English "Background") but it seems to take its editorial direction from Putin's RTDeutsch. While most conspiracy fans have moved on to other (CIA or Mossad-orchestrated) conspiracies (Charlie Hebdo, MH17, assassination of Nemzov, etc,), Russian media remains fixated on the idea that the CIA (with or without Israel) was behind the September 11, 2001 attack on the World Trade Center.
So it comes as no surprise that the current issue of Hintergrund features an interview with the architect and charlatan Richard Gage, who, for years has made a nice living giving lectures around the world on how the Twin Towers were brought down by explosives - not airplanes.
In the interview, Gage presents himself as a professional architect and engineer ("denn wir sind schließlich keine kriminalistischen Ermittler, sondern Architekten und Ingenieure") and demurs when asked who was responsible for exploding the towers:
Ich weiß es nicht… Ich denke, eine echte Untersuchung müsste zunächst mit einer vorbehaltlosen Beweisaufnahme beginnen. Und über die Macht verfügen, Zeugen zu laden, und diesen Immunität anbieten, um sie zu ermutigen, wahrheitsgemäß aussagen zu können. Das wären die Voraussetzungen, um den Kreis möglicher Verdächtiger eingrenzen zu können – wobei es sich wahrscheinlich nicht um Mitglieder Al-Qaidas handeln dürfte.
But it is clear that Gage, the Hintergrund editors, RT Deutsch, and many on the German left are absolutely convinced that the US government was behind the attacks. Most likely with the support of Israel - since a common myth is that the Israeli secret service Mossad sent a text message to 4,000 Jewish New Yorkers who worked at the World Trade Center telling them to stay home on Sept. 11(400 Jews evidently did not get the message and perished on that day).
The Tageszeitung reported on a 9/11 Truther presentation in Berlin and how the audience erupted in applause when the speaker blamed the attacks on "Jewish financiers" ("Der 11. 9. ein großer Plan des jüdischen Finanzkapitals").
As I've written before, anti-Semitism in Germany is the flip side of anti-Americanism.
Here is the 9/11 Truther Richard Gage on Putin's German channel RT Deutsch (Gage appears 14 minutes into the broadcast).
