As a Peace Corps Volunteer many years ago, I have maintained an interest in Nigeria as well as an affection for its people.    Your concerns and reactions to this sorry near-tragedy are interesting -- and worrisome and re-assuring at the same time.    The young man's life to this point is quite outside the mainstream of experience, both the wealth and the extremism     One of the first ideas that occurred to me is that he "lost himself"-- perhaps found an identity as a Muslim, rather than as an African or Nigerian.     It seems to me that his father might have had the goal of producing a cosmopolitan son, fluent in several languages, able to function anywhere on Planet Earth.
