A growing number of states now seek EU membership primarily for collective security and stability rather than for economic gain.
European integration is undergoing shifts in motivations: countries are increasingly approaching possible membership with a focus on security, not only on economic gain. If previously EU membership was perceived mainly as a path to wealth, now the benefits are viewed through the prism of stability and collective defense.
Two decades ago, when the governments of the former Eastern Bloc countries were leaning toward Brussels, the main argument was economic: a more developed West could raise wages and improve living standards. Now, however, global politics is changing, and economic dynamics are no longer the sole driver.
Countries with high economic potential, notably Iceland and Norway – which previously considered membership but settled on a different form of cooperation – are increasingly viewing the EU through a security lens. In the context of growing geopolitical risks and questions about the reliability of allies, European integration is seen not only as an economic contract but as a guarantee of stability and a shared defense and energy order.
Modern discussions about expansion tie decisions to a broader set of factors: harmonized standards, joint policies, and coordination in response to crises. For prospective EU members, the importance lies not only in income growth but also the ability to benefit from strong regional security mechanisms, energy stability, and joint measures in times of crisis.
The gradual shift toward security means that countries assess the partnership with the EU as a tool of stability at the regional and global policy level. For Iceland and Norway this means preserving autonomy in certain aspects of cooperation, while being in close alignment with the European Union and its regional structures.
Changes in enlargement motivations also affect negotiation processes with Brussels: countries weigh not only economic benefits but also the reliability of the security system, the level of integration into joint defense and energy projects, as well as the ability to respond jointly to global challenges, such as crises, migration, or cyber threats.
In the future, EU enlargement will most likely be viewed as a partnership where security and common commitments play a decisive role. It is important that Brussels offers clear guarantees and adequate instruments to respond to new challenges, in order to attract new countries and maintain stability in the region.
Thus, the future of EU enlargement will depend on how successfully the union can combine economic advantages with strong security guarantees and shared responsibilities.
