NATO Expert Talk Series: NATO and the challenges to the rules-based international order

NATO Expert Talk Series: NATO and the challenges to the rules-based international order



23 March 2022



Russia’s invasion of Ukraine and brazen aggression represent the worst military aggression in Europe for decades. It is also the most blatant breach of international law and state sovereignty on the European continent in a generation, which has, in turn, highlighted the importance of NATO’s core task of defence and deterrence. The aftermaths of the 24 February invasion will have irrevocable consequences for transatlantic security and priorities. Yet, even before this, there were multiple growing challenges to the existing security architecture and institutions that were set up in the wake of the Second World War.

What challenges and threats is NATO facing given the current security crisis on their eastern border? How will this impact the upcoming release of the new Strategic Concept? How can these issues be addressed both at the level of the Alliance and in cooperation with partner countries, such as Australia?

To discuss these issues, the United States Studies Centre (USSC) hosted an event with NATO's Head of Engagements Mr Nicola de Santis in conversation with USSC Senior Lecturer in US Politics and Foreign Policy Dr Gorana Grgic.

Jointly presented by the United States Studies Centre (USSC) and NATO Public Diplomacy Division; this event is part of a series of talks with USSC and NATO experts in which they explore the challenges ahead of NATO and Australia and propose areas where furthering and deepening cooperation can offer solutions.
