A more interesting read is the book he wrote as a followup to Mein Kampf ; Zweites Buch (which means "second book").

In it he lays out his multi-step plan which reads like alternative fiction...for one thing he expected the British to come down on the side of Germany (so the Axis would be Germany-Italy-Britain). He also planned on the final conflict for world domination (the war between the Axis and the US) to take place in the 80s.

But any of his writings are hard to read because it is really boring bloviating by a clearly hate filled schmuck ... if I wouldn't have been assigned them in school I probably would never have picked them up. Honestly Hitler makes Marx and Engels seem smart (although for historical perspective they're worth reading).

For contrast, you should also read the writings of our founding fathers ... Particularly The Federalist Papers (but not just them, our founders were prodigious writers). There you will find much better quality of writing and frankly a more enjoyable read (especially Ben Franklin's Poor Richard's Almanack ... every bit as fun to read as Mark Twain albeit not as sarcastic).
