With the Vilnius NATO summit fast approaching, we consider what arrangements need to be made to secure Ukraine’s sovereignty. The current focus of the international community is on sustaining and developing Ukraine’s warfighting capabilities to defend its territory and repel the Russian aggression. But ahead of the July NATO summit in Vilnius, attention is also turning to the task of ensuring Ukraine’s longer-term security, with pressure growing to grant Ukraine new security guarantees or even membership of NATO. While it is difficult to predict the exact situation that will prevail when major combat ceases, Russia is likely to remain a long-term threat to Ukraine’s sovereignty, society and economy, and the prospect of a return to full-scale war or a protracted conflict together with hybrid and disinformation operations remains high. In this episode, host Neil Melvin talks to Andriy Zagorodnyuk, Defence Minister of Ukraine from 2019 to 2020 and currently the Chairman of the Centre for Defence Strategies in Kyiv, about what arrangements need to be made to protect the future of Ukraine. What sort of security support will it need? What are the security arrangements that are being proposed at the Vilnius summit? And why are some NATO members reluctant to extend membership of the organisation to Ukraine?
