Publicity stunt?

The Chicago Council on Global Affairs has canceled an announced speech on the Lobby by John Mearsheimer and Stephen Walt.  We’re informed, from a letter by Mearsheimer and Walt, that this was done under pressure from critics who were uncomfortable with their arguments.  Do you think that the Lobby would be that stupid?  The ‘Court Jews’ wouldn’t be that obvious, would they?  Mearsheimer and Walt are arguing that the Lobby uses its inordinate power to censor discussion of its inordinate power, a thesis again proved by the actions of the Lobby in pressuring for more censorship.  Is it possible that this odd cancellation is a publicity stunt by the publishers of the Mearsheimer/Walt book?  Can’t you just see the dust-jacket blurb:  “The book the J-o-o-o-o-s don’t want you to read . . .”?
