He was nuts but to be fair he did try to make a deal with Israel . I give credit to Rabin for also trying too. Unfortunately some hardliner elements on both sides killed the deal. Ben Gvir was one of them (whom Netanyahu thinks is rational to have as a minister)….
“In the 1990s, he was active in protests against the Oslo Accords. In 1995, Ben-Gvir came to public attention for the first time, when he appeared on television brandishing a Cadillac hood ornament that had been stolen from Prime Minister Yitzhak Rabin’s car, and declared: “We got to his car, and we’ll get to him too.” Several weeks later, Rabin was assassinated by right-wing extremist Yigal Amir.”
