True, but the taxpayers should insist that cost overruns be kept no worse than the norm for national security expenditures... There should be big volume discounts. Not only would we need a lot for an attack, but the stuff won't have an infinite shelf life, so we'll be restocking this (or a new and improved version) periodically. Lawsuits should be prohibited if the government stockpile is actually used, thus holding down the drug company's risk and costs. Now if they want to further develop a commercial product for radiation damage of other sorts, e.g. late side effects of cancer therapy, then the normal rules apply for that separately.
Sounds Reasonable. But don't hold your breath, The feds negotiate like a 9 year old in a candy store.
