I would recommend reading historians who have written about Mein Kampf way more than the source material. I tried once. It was very difficult to make heads or tails of. Mostly it appeared to be the collected ravings of an extreme narcissist, and to pick out the actual policy bits requires more study than I was willing to put in. Fortunately, the book itself has been dissected in great detail over the years, and there are resources out there to get a glimpse of Hitler's political theory. I will highly recommend a new book on the topic, Black Earth by Timothy Snyder. It's by far the most insightful book I've ever read on the topic of Nazi thinking, how the Holocaust actually happened, and what the aims of the Nazi regime were vis-a-vis Jews and Slavs. I doubt it's been translated into Russian yet, as it's very new, but if you're comfortable reading it in English, it's a worthwhile read.
