The European Union has twenty-seven member states. Europe has roughly fifty countries.

The gap between those two numbers is not a failure of European integration. It is a map of the continent's complexity — a set of different relationships, different trajectories, and different reasons why countries that are geographically and culturally European have not become, or have chosen not to become, full members of the Union.

Understanding Greater Europe — the continent beyond the EU's formal borders — is essential to understanding how Europe actually functions. Trade, security, migration, energy, and political influence do not stop at the EU's external frontier. They flow across it continuously, shaped by the various frameworks that govern the relationships between the Union and its neighbours.

Those frameworks vary enormously. Switzerland and the EU have a relationship of deep integration managed through bilateral agreements. Norway and Iceland participate in the single market through the European Economic Area. Ukraine is a candidate for membership undergoing the most consequential transformation in its history. Turkey has been a formal candidate for nearly four decades with accession effectively frozen. The Western Balkans have been promised membership for twenty years with uneven progress. Moldova is accelerating its European path. Each relationship is its own story.

Switzerland is perhaps the most integrated non-EU country in the world.

It participates in the Schengen Area — no passport controls at its borders with EU neighbours. Swiss companies have access to the EU single market for goods through a dense network of bilateral agreements. Swiss universities participate in Horizon Europe, the EU's research funding programme. Swiss financial services have significant, though not unlimited, access to European markets.

Yet Switzerland is not a member of the EU and shows no serious political interest in becoming one. The reason is direct democracy. Swiss voters have repeatedly rejected closer EU ties when put to a referendum — most recently in blocking automatic adjustment of Swiss law to EU law changes, a sticking point that complicated the bilateral relationship for years.

The Swiss model is frequently cited by Brexit advocates as evidence that a country can be close to the EU without being a member. Swiss officials will tell you, usually privately, that the model is considerably more complicated than it appears from the outside — that the bilateral agreements require constant negotiation, that Switzerland effectively implements EU regulations in many areas without having any say in writing them, and that the relationship works because both sides have strong incentives to maintain it.

The United Kingdom left the European Union on January 31, 2020, following a referendum in June 2016 in which 52 percent of voters chose to leave.

The consequences have been significant, complex, and politically contested in ways that make a dispassionate assessment difficult in 2026. What is clear is that Brexit changed the relationship between the UK and the EU from one of full membership — with all its frictions and benefits — to one governed by the Trade and Cooperation Agreement, which provides tariff-free trade in goods but imposes substantial non-tariff barriers, excludes UK service providers from significant parts of the European market, and requires ongoing negotiation to manage divergence between UK and EU regulatory standards.

The relationship with Northern Ireland remains the most unresolved element of the post-Brexit settlement. The Windsor Framework of 2023 addressed some of the most acute problems, but the underlying tension — between Northern Ireland's position within the UK constitutional framework and its special trading relationship with the EU — has not been eliminated.

The UK remains deeply intertwined with Europe economically, culturally, and in security terms. It is a NATO member, a key partner in European intelligence sharing, and the continent's second-largest defence spender. What it is not, and will not be in any foreseeable political scenario, is an EU member again.

Russia's invasion of Ukraine in February 2022 transformed the enlargement map.

Ukraine and Moldova received EU candidate status in June 2022 — an unusually fast decision that reflected political urgency rather than technical readiness. Both countries have since begun formal accession negotiations, implementing EU standards at a pace that would have been politically impossible before the invasion.

Ukraine's case is without precedent. Accession negotiations are proceeding while a full-scale war is being fought on Ukrainian territory. Reconstruction planning is being conducted in parallel with active military operations. The EU has committed to a long-term financial support mechanism running to at least 2027, with the expectation that it will be extended.

Moldova is smaller and faces different challenges: its economy is fragile, its institutions are being reformed rapidly, and its path to accession runs through the resolution of the Transnistria question — the Russian-backed breakaway region that has controlled a strip of Moldovan territory since 1992.

Both accession processes are expected to take at least a decade in realistic assessment. Both carry transformative implications for the EU's demographics, agricultural markets, defence posture, and internal balance of power.

Greater Europe: Key Relationships at a Glance

EEA (Norway, Iceland, Liechtenstein): single market access, no political membership

Switzerland: bilateral agreements, Schengen member, no single market in services

United Kingdom: Trade and Cooperation Agreement, no single market access

Ukraine + Moldova: EU candidate status since 2022, negotiations underway

Western Balkans (Serbia, Montenegro, Albania, N. Macedonia, BiH, Kosovo): candidates or potential candidates

Turkey: candidate since 1999, accession effectively frozen

Georgia: candidate status since 2023

The six countries of the Western Balkans — Serbia, Montenegro, Albania, North Macedonia, Bosnia and Herzegovina, and Kosovo — have been promised EU membership since the Thessaloniki summit of 2003.

More than twenty years later, none of them are members. Montenegro and Serbia are furthest along in formal negotiations. Albania and North Macedonia opened accession negotiations in 2022. Bosnia and Herzegovina received candidate status in 2022. Kosovo, whose independence is not recognised by five EU member states including Spain and Greece, faces additional complications.

The slowness of Western Balkans enlargement reflects a combination of factors: reform fatigue in the candidate countries, enlargement fatigue in the EU, bilateral disputes between candidate countries and member states, and a strategic calculation by some Western Balkan governments that the EU path is too demanding and too uncertain to justify the political costs of reform.

The consequences are visible. Chinese and Russian influence in the region has expanded as EU credibility has eroded. Several Western Balkan countries maintain closer economic and political ties with both Moscow and Beijing than their EU candidate status might suggest. The gap between the promise of European integration and its delivery has become a strategic vulnerability.

Turkey applied for EC membership in 1987. It received candidate status in 1999. Accession negotiations opened in 2005.

In 2026, those negotiations are effectively frozen. The reasons are multiple: democratic backsliding under President Erdoğan, the unresolved division of Cyprus (an EU member that Turkey does not recognise), human rights concerns, and a strategic repositioning by Turkey toward a more autonomous foreign policy that positions it between Western alliances and alternative partnerships with Russia, China, and the Gulf states.

Turkey remains a NATO ally and a country of 85 million people with a large economy, strategic geography, and significant military capacity. It is too important to ignore and too complicated to integrate. The EU-Turkey relationship has settled into a permanent state of managed tension — cooperation on migration, occasional friction on everything else, and a formal accession process that neither side seriously believes will lead anywhere.

The most common misreading is to treat EU membership as the only meaningful measure of European integration.

It is not. Norway has more access to the European single market than most people realise — and more obligation to implement EU regulations without a vote in making them. Switzerland is so integrated that the distinction from membership is largely political rather than economic. Ukraine is undergoing institutional transformation that is reshaping its legal, judicial, and administrative systems in ways that will outlast whatever form its EU relationship eventually takes.

Europe is not a binary — member or outsider. It is a spectrum of relationships, each with its own logic and its own costs and benefits. Understanding that spectrum is essential to understanding how the continent actually works.

The European Union ends at its borders; European integration does not — and the difference between the two maps tells you more about the continent than either one alone.

The Western Balkans have been waiting for Europe for more than two decades. Friday's EuroTasteDaily Review examines what that wait has cost — and whether the promise of membership can still do the work it once did.
