"Iran is pursuing a nuclear program that includes significant capabilities, particularly its uranium enrichment and heavy water reactor capabilities that would provide Iran a nuclear weapons capability," Hammer says, adding that the capabilities "are not inherently capable of supporting Iran's stated objective of a peaceful nuclear power program."
Hammer says the body of evidence against Iran includes belligerent statements from Iranian officials, human intelligence sources and Iran's own military activity.
