TPQ’s Summer issue, NATO in 2020 and Beyond: New Strategies and Frontiers, offers insights on the Alliance’s current challenges and future security trends, while offering a look into Euro-Atlantic relations in the coming decade. It is clear that as the international security landscape is rapidly changing, member states’ capabilities, resilience, and most importantly, their commitment will be put to the test. In December 2019, NATO Leaders gathered in London to celebrate the Alliance’s 70-year history and assess the current state of transatlantic bonds. A growing list of both internal and external issues that will continue to be important for NATO were discussed, including Russia’s deployment of intermediate-range missiles, NATO’s expansion policy, China’s growing influence on the international stage, and strategic divisions among member states. The COVID-19 pandemic poses a particularly pressing challenge to NATO and its crisis response efforts. Headlining the Summer 2020 issue is NATO Assistant Secretary General Baiba Braze, whose article focuses on the Alliance’s resilience in response to the COVID-19 pandemic. Underlining the importance of multilateralism in the face of global crises, Braze explains NATO’s role in supporting wider efforts to fight the virus, while also critically preventing the health crisis from spawning security crises. Braze concludes by outlining NATO’s 2030 vision, which prioritizes making the Alliance stronger politically, as well as extending its global reach. Discussing the future of the transatlantic relationship in a declining liberal world order, Senior Advisor to the President of Turkey Gülnur Aybet argues that the policies of certain allies have forced Turkey to become a “self-help” state. Aybet illustrates a revised and inclusive liberal world order in which Turkey is understood in its own context, and thus, approached accordingly. Other topics taken up in this issue are the consequences of the INF Treaty’s demise and NATO’s digital public diplomacy efforts. Several of our authors discuss NATO’s expansion policy, including North Macedonia’s recent accession as the Alliance’s 30th member and the prospective memberships of Ukraine and Georgia.
