Netanyahu is old, 75 IIRC. His political future is not much anyways. He has devoted his life to protecting Israel from it's neighbors.
Has he? Netanyahu has devoted his life to Netanyahu's political career and his financial well being. Netanyahu has a salt and pepper relationship with Hamas. The goal with Netanyahu was never peace. After all, he did help fan the flames that got the Israeli PM Rabin murdered.
Yes.
Netanyahu has also lived his whole life as a survivor of the first war launched against Israel, moments after it came to be. I don't think Netanyahu has ever suffered from the delusion that Islamicists are interested in peace. So, of course, it's never been a goal.
Islamic neighbors to the north and southwest haven't been as nutty as they were in the beginning. It was proof that peace is possible. Sure, we have to pay off the Egyptian military, give Jordan lots of money, but it happened. We had the agreement in the 90s that Netanyahu helped get Rabin assassinated over. That was likely the chance that was squandered. I also feel the Hamas election was the final domino in that it wasn't even given a shot.
Peace with terrorists is a tough deal. But it isn't unprecedented, and using the past to perpetually justify more violence will never end the cycle. And Israelis and Palestinians will suffer as a result.
As things stand now, I can't see there being a peace. And Netanyahu is a significant piece in the puzzle as to why.
