What is the main conflict in By Way of Deception by Victor Ostrovsky?

By Way of Deception by Victor Ostrovsky is a fascinating book about the author's years in the Mossad, the Israeli intelligence service. He only worked for the Mossad for a period of four years, but he completed the three year training program and spent one year as a katsas. He was proud to be a part of the Mossad for the period he worked for them but then there was a botched operation in which his warnings were ignored. He was set up as a scapegoat and forced to resign. In addition, he was assigned front-line military duties the day after he resigned. This would have cost him his life. He fled from Israel and he and his wife and two daughters eventually settled in Ottawa, Canada.
