The paper by itself is questionable. It's apparently peer reviewed, but no journal is willing to publish it for now. One author asked for their name to be removed while others reviewers have dismissed its authenticity. It comes across as six of one and half a dozen of another. Either way, it's politically controversial if it's remotely true.
