The Center for Strategic and International Studies (CSIS) [2] said in a new report that low-yield tactical nuclear warheads would be one way for the Israelis to destroy Iranian uranium enrichment plants in remote, dug-in fortifications.   But other independent experts are on record warning that such a scenario is based on the "myth" of a clean atomic attack and would be too politically hazardous to justify. In  "Options in Dealing with Iran's Nuclear Program" [3] by the Ploughshares-funded think tank,  CSIS analysts Abdullah Toukan and Anthony Cordesman lay out the range of options available to Israel.
