I don't believe they are faked, just denied.
Its literally been proven as a forgery and fake.
Sources for the Protocols
The Protocols is a fabricated document purporting to be factual. It was originally produced in Russia between 1897 and 1903, possibly by Pyotr Ivanovich Rachkovsky, head of the Paris office of the Russian Secret Police, and unknown others.[2][3]
Source material for the forgery consisted jointly of Dialogue aux enfers entre Machiavel et Montesquieu or Dialogue in Hell Between Machiavelli and Montesquieu, an 1864 political satire by Maurice Joly[4] and a chapter from Biarritz, an 1868 novel by the antisemitic German novelist Hermann Goedsche, which had been translated into Russian in 1872.[5]
A major source for the Protocols was Der Judenstaat by Theodor Herzl although, paradoxically, early Russian editions of the Protocols assert that they did not come from a Zionist organization.[6] The text, which nowhere advocates for Zionism, resembles a parody of Herzl's ideas.[7]
Literary forgery
World literature includes a number of works employing the literary technique of the false document, presenting a work as an authentic text – the reader, however, will know of the fictional origin of the work.[8][page*needed]The Protocols is one of the best-known and most-discussed examples of literary forgery, with analysis and proof of its fraudulent origin going as far back as 1921.[9]
The forgery is an early example of "conspiracy theory" literature.[10] Written mainly in the first person plural,[a] the text includes generalizations, truisms and platitudes on how to take over the world: take control of the media and the financial institutions, change the traditional social order, etc. It does not contain specifics.[12]
