The Carnegie Endowment for International Peace recently released their report “Fire in the Hole: Nuclear and Non-Nuclear Options for Counterproliferation” http://www.ceip.org/files/pdf/wp31.pdf
This summary is from their website
The Bush Administration’s Nuclear Posture Review, leaked earlier this year, advocates new nuclear weapons designed to destroy underground bunkers and neutralize caches of chemical and biological weapons. A new approach to developing non-nuclear weapons for attacking underground bunkers and chemical and biological weapons is urgently needed. Research currently is too focused on weapons systems to the neglect of intelligence assets, and non-nuclear weapons are not being sufficiently explored. This new working paper compares the potential of new nuclear weapons with that of innovative non-nuclear weapons, demonstrating that proponents of tactical nuclear weapons have consistently overestimated their destructive potential while underestimating the battlefield problems they would pose. The report’s comprehensive review of non-nuclear technologies will be of immense assistance to anyone addressing weapons that might be used in a war with Iraq.
