<b>The greatest danger the world faces in the twenty-first century is an Iranian nuclear arsenal.</b> The nuclear deal currently before Congress may be the most important—and dangerous—policy decision of the twenty-first century. The deal is deeply flawed. But is rejecting a bad deal worse than accepting it? How did President Obama get us into this situation? And where do we go from here?<br><br>Alan Dershowitz has been writing and lecturing about the threat posed by Iran’s quest for a nuclear arsenal for more than a decade. He's discussed it with President Obama, with his national security staff, with Prime Minister Netanyahu, with high-ranking members of Israel’s military and intelligence communities, and with leading diplomats, scholars, and journalists. Now, in The Case Against the Deal with Iran, he presents the results of this decade-long encounter with the Iranian nuclear weapons program and its culmination in the Iran Deal.
