The role that nuclear weapons play in international security has changed since the end of the Cold War, but the need to maintain the human infrastructure for supporting nuclear capabilities and dealing with the multitude of nuclear challenges remains the same. For a number of reasons, including the diminished emphasis on nuclear weapons post-Cold War, expertise on nuclear issues – particularly within young generations – has declined. Unless the nuclear community makes a concerted effort to engage young talent now, cultivating the expertise critical to meeting the nuclear challenges of the future will become increasingly difficult. The 21st century’s complex geopolitical and budgetary environment demands a solid foundation of high-quality human capital across the nuclear enterprise. For this reason, in 2003, CSIS launched the Project on Nuclear Issues – to develop the next generation of policy, technical and operational nuclear professionals through outreach, mentorship, research and debate.
For the upcoming year, PONI has set four priorities for engaging the next generation:
- Promote 21st-Century Research for 21st-Century Scholars
- Engage the Full Next Generation Pipeline
- Build a Big Tent by Convening and Promoting New and Diverse Voices
- Demand and Provide Excellence
