The U.S. Department of Defense (DOD) has severed its 60-year ties to a group of academics known as Jason, putting in jeopardy the group’s ability to conduct studies for the government on a range of national security issues.

Jason, formed during the early years of the Cold War to provide the U.S. military with independent technical expertise, consists of some 50 scientists who spend part of their summer chewing over such knotty problems as maintaining the viability of the nation’s nuclear stockpile and the technical aspects of proposed weapons systems. Over the decades, other organizations have developed similar capabilities. But Jason has maintained its reputation for providing blunt and balanced advice to policymakers.
