The Perils of Tough Talk on Iran

For many years now the issue of Iran’s nuclear program has been at or near the top of the U.S. foreign policy agenda. For the most part the issue has been debated in strategic terms: Will deterrence and extended deterrence work on an Iranian nuclear weapons capability or not? What are the proliferation implications of an Iranian breakout? Would a nuclear weapons capability embolden or restrain Iranian policy? Politics tends to play a secondary role in serious analyses of such questions. It is not clear, however, that politics is necessarily a secondary factor, and the U.S. presidential election season is revealing how important it can be. In the end, political tails in the United States, Israel, Iran and elsewhere may wag strategic dogs. If they do, it would hardly be the first time history has recorded such a phenomenon.
