Writing a work of fiction

Yes I am tired of writing a series of serious opinions on the issues of the day and the facts out there, so it is definitely time to write a piece of fiction.

My ideas:

1. I write the book anonymously so nobody can possibly trace me or prove who I am, or can work out who could possibly have written this.
2. I claim to be a member of the team of US Navy seals who took out Osama Bin Laden but change the facts of history into fictional ones so that it makes my backers look good (even if one of them ran away to Paris for two years to get away from his only chance of fighting in a war, and none of his sons ever intend to) and the current incumbent looks bad.
3. I also change the ending so that Muslims round the world get really angry and start threatening us, and it makes the current incumbent look responsible. 
4. I have it published as close to the election as possible so that our side benefits and nobody has time to realise that it is a work of fiction. 
5. And old Rupert Murdoch is bound to offer me a ton of money for the serial rights down the road ....

So what do you mean "somebody has already done this?".
