Historical books by A. Bushkov.

I have a decidedly negative opinion of Bushkov as a historian. Firstly, he is not a historian and doesn't know how to work with historical information. Secondly, in his view, everyone else is a fool and a liar, while he is the only honest and intelligent person. Thirdly, consider this statement (from his book about Genghis Khan, I'm not quoting it exactly): "So what if I used to say that the Mongols didn't exist? Now I've changed my mind." That's an argument worthy of a kindergartener.
And he handles facts very loosely, using only those that support his views.
And, by the way, he didn't write the book about Beria :) (The author of that book is Elena Prudnikova).
