Michael I. Karpin (Hebrew מיכאל קרפין, born on 29 November 1945) is an Israeli broadcast journalist and author, best known for his investigative documentaries and books, revealing two of Israel's most concealed affairs: The creation of the country's nuclear capability and the nationalistic-messianic incitement campaign that preceded the assassination of Prime Minister Yitzhak Rabin. On May 1986, Karpin broke the story of Israel's secret service (Shabak) fabrication of evidence in the course of Bus Line 300's investigation, one of the most controversial political affairs in the history of the country. In 1987, he exposed the Izat Nafsu Affair: a Moslem IDF officer and a Circassian (a small ethnic minority in Israel), who was maliciously investigated by the secret service, convicted of spying and eventually exonerated by the Supreme Court. Karpin is married to Pnina (née Bahat), has 3 grownup children and lives in Tel Aviv.
