NARRATOR: For years, the Israelis have paid the price of living a life of no war and no peace.

Bomb threats and acts of terror have become a part of the Israeli reality.

There has always been Arab terror in the Israeli street. But then some thing new happened, terror was taken into the Arab street. Arabs were maimed and killed and bombed by Jews and a new term began to appear -- Jewish terrorist, and a Jewish underground.

Hagai Segal was part of the Jewish underground. He had planted a bomb in the car of the Arab mayor of Ramallah, who lost his leg in the explosion. Segal was sentenced to three years in jail. He got out after two, in May 1986.

HAGAI SEGAL, Member, Jewish Underground: As I said in the trial, I am at peace with what I've done. A few of our friends said they were sorry. I was not one of them. I feel that the people who are hurt deserved what they got.

It was in 1980, the security situation on the roads here was at its worst. Everyone of our trips was accompanied by stones thrown at us, and hand grenades. And it ended with the murder of six men in Hebron. That's when I decided that something had to be done. Some people came to me saying there was a plan for reprisal, will I join? I said yes. Then we did some intelligence work in the field, and then we planted the bombs.

NARRATOR: He doesn't see himself as a terrorist.

HAGAI SEGAL: I see myself as someone who is fighting for his home, his children. If that's the definition of a terrorist, then I am one. If not, then I'm not.

Interviewer: Were you horrified when you heard about what happened?

Hagai Segal's Mother: If you mean by horrified that suddenly my son is in prison, maybe that fact horrified me, but the reason for it not at all. I felt that that was the natural conclusion of the education that he's received since he's received since he was born, one can say.

Interviewer: Namely. . .

Hagai Segal's Mother: Namely that uh, we've always understood that this country belongs entirely to us, and if we can't get it in peaceful ways we have to get it in other ways.

Interviewer: Were you proud of him?

Hagai Segal's Mother: I was proud of him, definitely, there wasn't one single second -- from the time I heard until this minute -- that I wasn't proud of him.
