John Leifer

John Leifer is deeply immersed in national defense issues, particularly the proliferation of weapons of mass destruction. His perspective is shaped by interactions with key government agencies, independent scientists, and noted observers, including interviews with leading figures in nuclear weapons design and Nobel laureates. His service on a presidential panel post-9/11 has provided him with unique insights into intelligence community information sharing. Beyond defense, Leifer writes extensively on healthcare, drawing on over three decades of experience working with leading hospitals and healthcare systems.
