This council will focus on the future of the International Security system and how to shape it. The following dimensions have been highlighted: - Strategic stability: what should be done to ensure technological capabilities are used in ways that maintain stability and promote a better level of international security as a global common good? What can be done to achieve better mutual understanding and transparency, reducing the risks of miscalculation? How can we avoid a future where technology favours the offensive, or emboldens aggression? What opportunities exist to use technology to solve familiar and new security challenges? - A shift in the public / private balance: Much of the enabling technology for the 4th Industrial Revolution is originated, developed and exchanged in the private sector, where R&D budgets far exceed those of many industrialised countries. The scope for "dual purpose" technologies is increasing too. How will this affect issues like arms control regimes, proliferation, and the balance of power between state actors and non-state actors? - New domains: powerful, cheap and freely available technology is lowering barriers to entry in new domains such as cyber, space and the ocean depths. Where regimes of governance lag behind, this can tempt security actors to explore new operational courses of action, and prompt new arms races. What are the most pressing areas for action on governance, and what other approaches can be considered for preservation of global security?
