This book provides an overview of U.S. led sanctions being imposed on Iran. There is broad international support for imposing progressively strict economic sanctions on Iran to try to compel it to verifiably confine its nuclear program to purely peaceful uses. However, there is not a consensus on how effective the sanctions are on core Western goals. In January 2011, Secretary of State Clinton claimed that sanctions have accomplished a core objective of slowing Iran's nuclear program. But, nuclear talks in December 2010 and in January 2011 made virtually no progress, suggesting that Iran's leaders do not feel sufficiently pressured by sanctions to offer major concessions to obtain a nuclear deal. Because so many major economic powers have imposed sanctions on Iran, the sanctions are, by all accounts, harming key sectors of Iran's economy by reinforcing the effects of Iran's economic mismanagement.
