Bibi is right about one thing. The negotiating challenges have become more difficult since Arafat’s refusal of our offer at Camp David. Arafat is no longer alive. Palestinian politics have become ever more fragmented and messy, not least as a result of the Hamas takeover of Gaza. But Churchill once said that the difference between a pessimist and an optimist was that the pessimist always saw difficulties in every opportunity. The optimist saw opportunities in the difficulties. I, of all people, do not look at such opportunities without hard-headed analysis, even a dose of scepticism.

Seriously. What do you have to lose?” But beyond this, there is a whole range of relatively moderate countries — and, as Sunni states, strongly anti-Iranian countries — which share with Israel a real, practical interest in putting in place a new political arrangement in the Middle East.
