We look at the nuclear powers and those who want to join their club. Are nuclear weapons a deterrent or a strategic show of strength? We examine what treaties are in place to control the use of nuclear weapons and how they work in practice. Are there enough checks and balances to stop escalation? Claire Graham talks to the BBC’s security correspondent Frank Gardner.
