The CIA and September 11

The CIA and September 11 (German: Die CIA und der 11. September) is a 2003 non-fiction book by Andreas von Bülow, a former state-secretary in the German Federal Ministry of Defence and a Social Democratic member of the Bundestag from 1969 to 1994. The book disputes al-Qaeda's responsibility for the September 11 attacks and suggests that it may have instead been a false flag operation arranged by the U.S. federal government and Israel. The book has enjoyed considerable commercial success in Germany, where it is published by Piper Verlag, and has sold over 100,000 copies. However, it has faced allegations ranging from absurdity and fostering anti-Americanism, to antisemitism, while the quality of its sourcing and the timing of its publication have given rise to debate within the German publishing industry. In subsequent media appearances, Bülow has defended his work, and strongly denied that its content is antisemitic.
