Rouhani was elected president because he offered hope; he claimed that the nuclear agreement would be the key to unlock or solve Iran's problems. But it will take more than that to make Iran a better place to live. Can he achieve his people's dreams? Is he even willing?
It is no surprise that the final Iran nuclear deal was met with opposition in Israel and Saudi Arabia. For all the talk about whether or not this is a good deal, negotiating with Iran was the original sin from their perspective.
Escalating competition among major powers is amplifying the role of nuclear weapons in defense policies, including more easily used — and thus especially dangerous — tactical nuclear forces. Before it becomes too late, the U.S. should design and lead a new campaign to control nuclear risk.
Even a strong nonproliferation agreement that prevents all pathways toward the Iranian bomb won't magically transform the Middle East. But on balance, the region would be better off with a good nuclear deal than without one.
