Congress and the Prime Minister of Isreal have demanded that the P5 negotiate a "better" deal than the one contemplated in recent Iranian Nuclear Framework.
While negotiating in the abstract has some limited value, it would be more instructive if specific examples of recent international agreements between adversaries where one side completely capitulated to the other would be a valuable template for the P5 to reference prior to a final agreement.
Given the expertise of Isreal's current Prime Minister in the area of forging tough agreements with adversaries, he should certainly have 3 or 4 examples of agreements that he has recently negotiated with adversaries that can be used as "success templates".
