The interim deal on Iran’s nuclear program, secured in late November 2013 and implemented from January 20, 2014, was intended to create space for the tough negotiations over a comprehensive deal that would close the Iranian nuclear file. The essays compiled in this volume analyze some of the key issues that have emerged regarding efforts to carve out a “good” nuclear deal with Iran, and highlight additional perspectives that have not been at the heart of the debate. Discussed in this collection are general principles for negotiating with Iran, Iran’s advances in the nuclear realm, the effect of economic sanctions, and the US-Israel-Iran deterrence triangle. The broader context is addressed in essays that consider Iran’s possible shift to a more moderate stance, the status of the military option, and US public opinion on talks with Iran. Regional perspectives focus on Israel, the Gulf states, and Turkey, and the volume closes with an essay that lays out the contours of an acceptable deal from Israel’s point of view.
