The israeli leadership is incompetent. Iran probably already has a nuclear weapons... Just afraid to test them and let the world know until they have a reliable way to deploy them. Just like israel duped inspectors back in the day, Iran has done the same. I do not agree with everything Israel does but Israel just backed theirselves into a corner with Saudi Arabia... Saudi Arabia will collapse if Iran gets nuclear weapons within ten years, so better act quick.
