The European Commission has now declared enlargement a “geopolitical imperative” – with important implications.

The bloc has just presented a package of reforms designed to prepare the Union for new members – with Ukraine and Moldova at the center of the effort, alongside Albania and Montenegro.

Commission President Ursula von der Leyen stated that “Europe’s future depends on the choices we make today,” framing expansion as essential to making the bloc “more resilient” and better able to shape its own destiny.

Candidate countries are already advancing: Ukraine and Moldova opened their first negotiating cluster in June 2026, and in July, opened Cluster 6 on external relations, foreign policy, security and, importantly, defense. In the words of Vessela Cherneva: “Currently, EU membership is the only way to integrate Ukraine’s and Europe’s security systems.”

The Commission plans “indicative roadmaps” for these four frontrunners (Ukraine, Moldova, Montenegro, and Albania) in its 2026 Enlargement Package, provided reform momentum continues. Gradual integration into strategic sectors such as energy, transport, digital networks and defense is explicitly on the table

This is no longer presented as a purely technical or economic process. Again, Brussels itself now describes enlargement as a “geopolitical” tool linked to European safety, prosperity and security. One may recall that earlier enlargement rounds were often framed in terms of shared values and market access.

Political scientist John Mearsheimer has long argued that the West’s “triple package” of policies – NATO enlargement, EU expansion and Western-style democracy promotion – added fuel to a fire waiting to ignite – meaning the Ukrainian crisis since 2014.

Actually, in his view, the trouble over Ukraine began in earnest at NATO’s 2008 Bucharest summit, when the alliance announced that Ukraine and Georgia “will become members”.

Russian leaders treated this as an existential threat. Washington ignored the red line and continued to push Ukraine toward Western institutions, including closer ties with the EU.

Back in his 2014 analysis Mearsheimer noted that the Union’s eastward march and the Eastern Partnership initiative were viewed in Moscow as hostile enough. “In the eyes of Russian leaders, EU expansion is a stalking horse for NATO expansion,” he wrote.

In this framework, the West’s efforts to promote “democracy” and “peel Ukraine away” from Russia completed the package. When Yanukovych rejected an EU deal in 2013, the “spark”, as Mearsheimer puts it, came. The result was crisis, then war. If one applies that framework consistently today, the resulting picture is quite straightforward.

To be clear, EU membership is not identical to NATO membership. Yet from a Russian great-power perspective the distinction becomes less meaningful when the two institutions are moving in the same geographical direction.

EU accession after all entails progressive alignment on law, foreign-policy positions, sanctions, energy, borders and increasingly elements of security and defense cooperation. The point is that an EU-member Ukraine would be economically, legally, institutionally and politically embedded in a Western bloc – and the same applies to the other Eastern European states. That, in broad terms, is precisely the structural transformation process Mearsheimer argued helped fuel the 2014 and then the 2022 crisis.

Ukraine remains the clearest case in point: before 2014 it functioned as a contested buffer. Mearsheimer (as well as specialists of the caliber of Henry Kissinger and Stephen Walt) argued a neutral Ukraine would be preferable, from a Western perspective – akin to Austria during the Cold War. In any case, the trajectory now points toward full Western institutional integration.

Moldova is arguably just as sensitive: it has a Russian military presence in Transnistria, occupies a strategic position between Ukraine and Romania – and is accelerating toward EU membership while deepening practical cooperation with Western militaries.

The recent Independence Day parade in Chișinău illustrated the point (without Soviet symbology, for the first time), as I’ve commented: Moldovan troops marched with Western weapons and vehicles; contingents from the Ukraine and eight NATO members, including the US, took part. NATO’s Political Committee had visited just days earlier, describing intensified cooperation.

Moldova for its part remains formally neutral, yet it is simultaneously negotiating EU accession – including the cluster on external relations and defense policy – and publicly displaying Euro-Atlantic partnerships.The Western center of gravity (post-USAID) in Moldova is shifting toward Brussels, which has stepped in with a large Reform and Growth Facility.

From Moscow’s point of view, the cumulative process looks like progressive incorporation of its western strategic environment into a Western political-security system.

Historically, great powers care intensely about the direction of strategic change in their immediate neighborhood. They typically do not wait until the process is complete before reacting – as seen in 2022.

In any case, the EU now frames enlargement itself as a geopolitical and security instrument. This language reinforces the very security dilemma Mearsheimer identified over a decade ago. The buffer zone between Russia and the Western institutional order continues to shrink. The risks of further escalation keep rising eastwards – adding to the tensions farther north, in the Baltic.

The European Commission has proposed new safeguards allowing voting rights and funding to be restricted if future EU members breach fundamental European rules after accession, as Brussels prepares for possible membership of Ukraine, Moldova, Albania and Montenegro.

The European Commission has set out a new framework for enlargement that would allow the European Union to impose restrictions on recently admitted countries for up to 15 years after accession if they retreat from commitments on democracy, the rule of law or other fundamental EU principles.

The measures form part of the Commission’s new pre-enlargement policy review, published on Tuesday, which examines how the EU’s institutions, budget and policies would have to change before another round of expansion. Brussels says the Union could accommodate additional members without rewriting its treaties, but would need stronger safeguards to prevent enlargement from making decision-making more difficult.

Under the proposals, accession treaties could contain an institutional safeguard allowing action against a new member that seriously breaches the values contained in Article 2 of the Treaty on European Union or the principle of sincere cooperation. In the most serious cases, Council voting rights could be suspended.

The Commission’s public summary describes those arrangements as temporary, targeted and reversible. Reporting on the underlying proposal indicates that the enhanced safeguard could remain available during the first 15 years of membership.

The proposal addresses a problem that has moved steadily up the enlargement agenda: how to ensure that a country continues to meet membership conditions after it has entered the EU.

Germany, France, Belgium, the Netherlands and Luxembourg had already raised the issue earlier this year. As EU Today reported in June, the five governments called for mechanisms capable of restricting some rights of new members if democratic standards deteriorated after accession.

The Commission has now turned that political argument into a wider institutional proposal.

The change is particularly relevant to Ukraine, Moldova, Montenegro and Albania, which Brussels identifies as the four candidates currently furthest advanced. The Commission says it will prepare indicative roadmaps for each country provided reform momentum continues.

Ukraine and Moldova may also make further progress within days. EU Today reported earlier on Tuesday that two more negotiating clusters could potentially be opened next week if Ukraine’s parliament passes legislation dealing with minority-language education.

Alongside stronger rule-of-law safeguards, the Commission wants candidate states to be integrated gradually into parts of the EU before full membership. Energy, transport, digital policy and defence are among the sectors identified for deeper participation.

Brussels is also proposing greater use of qualified-majority voting during the accession process, including for decisions to open negotiating clusters. At present, individual governments can delay progress at several stages because unanimity is required.

Another proposed safeguard would require a newly admitted state, for a limited period, not to block subsequent enlargements because of bilateral disputes. The measure reflects long-standing difficulties in the Western Balkans, where disputes between neighbouring states have repeatedly entered accession negotiations.

Ukraine’s agricultural sector presents a separate challenge. The Commission says transitional arrangements could be used for agriculture, sensitive products, EU funding, the movement of workers and participation in common systems. Reporting on the package indicates that unrestricted access by Ukraine to existing Common Agricultural Policy support is unlikely immediately upon accession because of the scale of Ukrainian farming.

That question is politically important for existing agricultural beneficiaries, particularly in Central and Eastern Europe, where Ukrainian grain and food imports have already caused disputes.

The institutional proposals do not guarantee membership for any candidate. Accession remains dependent on meeting the EU acquis, completing negotiations and obtaining the agreement of existing member states.

Nor has the 15-year safeguard yet become EU law. The Commission has asked the European Council and European Parliament to take forward discussions, and the eventual provisions would have to be reflected in future accession arrangements.

What has changed is the shape of the enlargement debate. Brussels is no longer concentrating solely on what candidate countries must do before joining. It is also designing mechanisms governing what happens after they enter.

For Ukraine, Moldova and the Western Balkans, that could produce a more credible path towards membership, but one accompanied by conditions extending well beyond accession itself.
