Excellent. The author will be pleased. Nothing is better to boost sales than by banning something. I hardly think that the CIA's and MI6's engineering of the Soeharto coup and their accompanying death lists are something to pretend didn't happen any more.
If someone thinks they have been libelled by a book, they should sue its publishers in court. Surely this is nothing to worry about now though: the few people who survived those dark times have their hands clean.
If anyone wants to hush up what the CIA did then surely it would be the CIA themselves, wouldn't it?
Why do their work for them and be more enthusiastic they are? Don't be silly.
