In 2015, following lengthy negotiations, President Barack Obama concluded an executive agreement marking the accomplishment of a cherished policy goal: the nuclear deal with Iran known as the JCPOA. Also in 2015, after similarly lengthy negotiations, Prime Minister Benjamin Netanyahu concluded an agreement realizing a long-cherished policy goal of his own: a deal enabling development of Israel’s largest natural-gas field by a private American company and its Israeli partner. Both agreements included a commitment by the respective governments to refrain from adverse legislative action over the next ten to fifteen years: in Obama’s case, action to reinstate nuclear sanctions against Iran; in Netanyahu’s case, action to alter the regulatory regime for natural gas to the disadvantage of the private energy companies.
