Iran's advanced nuclear program may be the world's most important emerging international security challenge. If not stopped, a nuclear-capable Iran will mean an even more crisis-prone Middle East, a potential nuclear-arms race in the region and around the world, and an increased risk of nuclear war against Israel and the United States, among many other imminent global threats. Matthew Kroenig, internationally recognized as one of the world's leading authorities on Iran's nuclear program, explains why we need to take immediate steps to a diplomatic and, if necessary, a military solution--now--before Iran makes any further nuclear advances. "A Time to Attack "provides an authoritative account of the history of Iran's nuclear program and the international community's attempts to stop it. Kroenig explains and assesses the options available to policymakers, and reflects on what the resolution of the Iranian nuclear challenge will mean for the future of international order. This dramatic call to action provides an insider's account of what is being said in Washington about what our next move must be as the crisis continues to develop. "Thankfully, Matthew Kroenig has written a compelling book that takes a serious analytical look at the Iranian nuclear program. Even those who oppose his position would be well advised to consider his well-reasoned arguments." -- Ambassador Dennis Ross, Former Special Assistant to President Obama and Senior Director for the Central Region, and author of "The Missing Peace: The Inside Story of the Fight for Middle East Peace" "Matthew Kroenig's "A Time to Attack" is the most thorough book-length examination of the issues involved in assessing the Iranian challenge. Clearly and engagingly written, "A Time to Attack" is a major contribution to the national debate on the issue and is a must read for any and all who would venture to put forward an opinion on this vital topic." -- Ambassador (ret.) Eric S. Edelman, Former Under Secretary of Defense for Policy, 2005-2009 and co-chair of the Gemunder Center Iran Task Force "Matthew Kroenig is a smart, serious expert whose provocative arguments on Iran policy...will inform and sharpen your thinking about Iran, nuclear proliferation, and American foreign policy more generally." --Gideon Rose, Editor, "Foreign Affairs" "As someone who has written a book making the exact opposite argument of "A Time to Attack", I want to commend it to anyone interested in the question of Iran's nuclear program and what America should do about it." --Kenneth M. Pollack, author of "Unthinkable: Iran, the Bomb, and American Strategy"
