They Rise or Sink Together: NATO on the Road to Vilnius

NATO’s summit in Vilnius will be another step on the pathway to building a new European security architecture. NATO leaders will consider the further changes needed to their defence posture to ensure the credibility of the Alliance’s updated collective defence plans, perhaps raising difficult questions about defence spending, and exposing gaps between the eastern and other Allies in threat perceptions and appropriate strategies for response. NATO enlargement will also be a key topic, with Sweden still waiting in the wings over Turkey and Hungary’s objections, and many Allies seeking at least some form of security guarantee for Ukraine. Meanwhile, a rising China and continuing instability to Europe’s south demand an international response.

What more does NATO need to do to counter the threat from Russia? How can Alliance unity, strengthened enormously after Russia’s full-scale invasion of Ukraine, be preserved? What can NATO offer Ukraine? What is NATO’s role in relation to the growing ambitions and belligerence of China, and to challenges on its southern borders?
