This is an anthropology book aimed more at business travelers than tourists or lovers. It is based substantially on his personal experience, which is at least authentic, but limited, for such a large area. Note that Russia is not included in this volume--it rates its own book. The generalizations are necessarily broad, but they are more insightful than the traditional ethnic stereotypes. There is hardly any science here, and you will be disappointed if you are an anthropologist. On the other hand, if you are businessperson who had assumed that everyone is pretty much like your fellow Americans, it will be an eye-opener.
Of course, quite a bit has changed since 1995. The effects of the 2008 crash and the 2009 Russian anti-American propaganda campaign are not anticipated here. The author was right about the instability of Crimea.
