To avoid the worst, Israel must remain strong in spirit and ready to act preemptively.
While Netanyahu is PM, I think that's a safe bet. Here's an excerpt from an article earlier this year....
[Journalist Jeffery] Goldberg also quotes "friends and advisers" of Netanyahu who say that he took three lessons from his brother Yonatan’s death, in the heroic raid on Entebbe in 1976: "The first is that those who threaten Jews, and have the means to carry out their threats, should be neutralized pre-emptively. The second is that no one will defend the Jews except the Jews themselves. The third is that destiny has chosen the Netanyahus to expose and battle anti-Semitism — before it reaches the point of genocide."
