This book reviews the status of Ethiopian Jews through recent comprehensive research of the roots of Jewish identity. The author argues that Jewishness cannot be determined by scientific and sociological methods alone, but is a function of Halakha (Jewish Law). Consequently, whereas "historical truth" is uncertain, it is "Halakhic truth" which is definitive for Jews. These issues revolve around one crucial question: "who is a Jew?"
The upsurge of Aliyah from Ethiopia peaked with "Operation Moses" in 1984-1985, and "Operation Solomon" in 1991, rescue airlifts that resonated around the globe. This immigration of 70,000 Jews, including the current return of the Falas Mura, has intensified debates on questions concerning the Law of Return.
