The subject of international security is never out of the headlines. The subjects of war and peace, military strategy, the proliferation of nuclear weapons and revisionist states remain central to the discussion, but burgeoning concerns such as climate change, migration, poverty, health, and international terrorism have complicated the field. So what really matters? The traditional prioritization of state security or the security needs of individuals, humanity, and
the biosphere? And where do the problems lie? Are states themselves as much a part of the problem as the solution for people's security needs? With globalization, the international security environment has become more interdependent than ever before with the establishment of complex networks that make
responding to and managing security challenges increasingly difficult, but increasingly necessary.
