Obviously all the Arab states weren't "keen" on the idea of an Israeli state and tried to destroy it then and continue to do so, all to no avail.. I would have to think if there were no Israel in the ME, the Arabs would continue killing each other as they had in the past. Good thing there's an Israel, now they collectively have someone to hate. They had the land for centuries and did nothing with it, Israel was there for a few decades and made the desert bloom.
