ONN Engagement Network

The ONN Engagement Network is a carefully selected team of high level trusted and credible individuals, including retired military and foreign policy officials, and other well‑regarded experts, who have knowledge, experience and access to nuclear decision makers and individuals associated with them. Members of the Network are external affiliates, but work in close collaboration with ONN staff. With conflict de-escalation at the centre of their mission, they work to identify opportunities for engagement when conflict is on the rise, providing neutral, objective information as a means of reducing nuclear risk.

Network members receive regular briefings from ONN analysts, and convene meetings with decision makers, as necessary, to provide information in the service of de-escalation.
