A Shift in Motivations for Joining the European Union
According to an analysis by Politico, the primary motivation for nations seeking to join the European Union has transformed. The focus has shifted decisively from economic benefits to security concerns. This fundamental change has been driven by Russia's full-scale invasion of Ukraine in 2022 and the foreign policy stance of the Donald Trump administration, which returned to the White House in 2025. The article also examines potential candidates for EU membership, including Iceland, Norway, Canada, and Ukraine, alongside the significant challenges facing the bloc's enlargement.
Iceland has notably accelerated its timeline for a referendum on resuming EU accession talks, signaling a clear shift in its national priorities. Since 2004, 13 countries have joined the EU. The current official candidate countries for membership are:
- Ukraine
- Moldova
- Albania
- Serbia
- Montenegro
Norway, which first applied for membership in 1992, and Iceland, which applied in 2009, have experienced various stages of negotiations. Iceland froze its talks in 2013 and formally withdrew its application in 2015.
The United Kingdom's vote for Brexit in 2016 also reshaped the European political landscape, which in turn has increased interest in EU membership from other nations. The EU treaty contains a key mutual defense clause—Article 42.7—highlighting the bloc's security dimension. As European Commissioner for Enlargement, Marta Kos, stated:
“EU membership has always provided stability and prosperity for European nations.”
Shifts in the international order are influencing candidate countries. Iceland's Foreign Minister, Thórdís Kolbrún Reykfjörd Gylfadóttir, emphasized the security imperative of membership: “We would be stronger as part of a large group of like-minded nations that stand up for democracy, freedom, human rights, and territorial integrity.” Norway, with its established democratic institutions, is also reconsidering accession, noting the distinct tools offered by NATO and the EU. As conservative leader Ine Eriksen Søreide explained:
“NATO has one set of tools, the EU has another.”
Ukraine's position is particularly significant. According to Ukrainian government advisor Ivan Nagornyak, Ukraine could strengthen the EU's defense: “We have a shared interest. Ukraine can bolster EU defense. Just imagine: Ukrainian border guards, who have fought on the front lines, carrying out Frontex missions in the Baltic Sea.” Projections for 2026 estimate Ukraine will rank 132nd globally in GDP per capita, a factor that will also influence its accession prospects.
Implications for the European Union
This evolution in motivation reflects the new security realities in Europe, shaped by external threats and internal political changes. Time will tell how these factors will influence the future of the European Union and its enlargement process.
The renewed focus on security underscores the serious global challenges Europe currently faces. This pivot may lead to new strategies and initiatives within the EU aimed at bolstering defense capabilities and political unity. Simultaneously, the bloc's expansion could become a crucial step for integrating new partners who seek stability and security within their regions. This strategic realignment marks a pivotal moment for the EU's role on the world stage.
As the EU navigates its evolving landscape of membership aspirations, the urgency surrounding Ukraine's accession discussions by 2027 underscores the bloc's commitment to enhancing security ties among candidate nations. This strategic shift is indicative of broader geopolitical trends that are reshaping priorities across Europe.
