Europe's rearmament surge is forcing Austria, Ireland, Malta and Cyprus to reckon with neutrality policies rooted in Cold War history — as Russia's invasion of Ukraine and warnings of potential NATO conflict by 2030 test whether non-alignment can survive in a continent racing to rebuild its military capabilities.
The four EU countries maintain policies of neutrality or military non-alignment, though their legal status and interpretation differ. Austria and Malta have neutrality enshrined in their constitutions. Ireland's military neutrality is deeply entrenched. Cyprus has historically pursued a policy of non-alignment, a position increasingly tested by closer defence ties with the West.
Constitutional Constraints Meet Strategic Reality
Austria enshrined neutrality in constitutional law 71 years ago after the post-World War Two restoration of its sovereignty. When Austria applied to join the EU 37 years ago, the European Commission said its "permanent neutrality" was incompatible with provisions of the existing treaties and could pose problems for the bloc's emerging common foreign and security policy. Austria nevertheless joined the EU 31 years ago.
Arnold Kammel, Secretary-General of Austria's Federal Ministry of Defence, said neutrality has shifted since EU accession. "Neutrality has somewhat changed its meaning, however, the core substance of remaining neutral is heavily enshrined in the DNA of the Austrians, and thus it seems also to continue in the future," he said. Austria aims to raise defence spending to 2% of GDP by 2032.
The European Commission now says security and defence choices remain a national competence, meaning EU treaties don't prevent Austria, Ireland, Cyprus or Malta from maintaining their neutrality. In practice, neutrality doesn't prevent the four from supporting Ukraine, including through EU financial assistance such as the €90 billion loan, and sanctions against Russia. Cyprus and Ireland have also joined the Coalition of the Willing, while Austria remains an observer.
The Mutual Defence Question
Neutrality also doesn't remove their obligations under Article 42.7 of the EU Treaty, the bloc's mutual assistance clause. It requires member states to provide aid and assistance "by all the means in their power", while preserving the specific character of countries' security and defence policies. It doesn't automatically require a neutral state to provide military assistance.
France invoked Article 42.7 11 years ago after terrorist attacks. Austria didn't provide direct military assistance, citing neutrality, but supported UN and EU missions elsewhere. For Austria, any response would require domestic political consultation "within the limits that are given to us by our constitution", Kammel said.
Cyprus Breaks Ranks
Cyprus has historically pursued a policy of non-alignment, but President Nikos Christodoulides has suggested a break. In May, Christodoulides said the divided country was ready to join NATO "when political conditions allow". Turkey's opposition is the principal political obstacle given NATO's consensus requirement.
2 months ago, Cyprus began receiving funds under the EU's Security Action for Europe (SAFE) programme, with up to €1.2 billion available for defence investment. It's the only neutral or non-aligned EU state to receive SAFE funding, which is reportedly earmarked for drones, anti-tank missiles and ammunition.
Christodoulides said: "Europe that does not invest in its defence and security is a Europe that is dependent, and dependence cannot be a strategic choice, if we want — and yes, we do want — to be geopolitically strong."
The British sovereign base in Cyprus' Akrotiri was struck by an Iranian-made Shahed drone 5 months ago. Christodoulides said the incursion shows the need for a "clear manual that ensures the union acts as a credible guarantor of security."
Steven Everts, Director of the EU Institute for Security Studies, said most of Europe's neutrality is rooted in history but all EU member states must reckon with the realities facing them in 2026. "The speed at which the world is changing requires everybody to assess whether the choices made decades ago — or 70 to 80 years ago — still apply to the world you live in today," he said.
Ireland's Peacekeeping Tradition
In July, Irish Prime Minister Micheál Martin clarified that Ireland is militarily but not politically neutral. "Since World War Two, Irish people have remained steadfastly loyal to the principle of military neutrality, which is basically not being a member of any military bloc or military alliance, so in effect, we're not members of NATO," he said.
He added that Ireland cooperates with NATO through the Partnership for Peace on critical undersea infrastructure, cybersecurity and hybrid threats. Ireland has built a reputation for international peacekeeping, including in Kosovo and Afghanistan. Ireland's policy of military neutrality was formally adopted in the run-up to the Second World War about 86 to 87 years ago and has since been maintained by successive governments. It's not enshrined in the Constitution.
Martin said Russia's war had prompted Finland and Sweden to join NATO, but had not altered Irish public opinion. "It is the overwhelming wish of the Irish people to remain militarily neutral," he said.
8 months ago, the government announced a record €1.7 billion in capital investment for defence package for 2026–2030, aimed at strengthening capabilities across land, air, maritime and cyber domains.
Ian Lesser, distinguished fellow at the German Marshall Fund think tank, said Ireland's reliance on others while not being able to "shape" wider security strategy puts it in an awkward position, particularly in cybersecurity given Dublin's concentration of tech giants. "Ireland is highly dependent on its international digital links, and the security of the sea lane around Ireland is something that cannot be taken for granted," he said.
Malta's Balancing Act
Malta's obligations to uphold the bloc's security and defence while also respecting its constitutional imperative to remain neutral is described as a fragile act. Daniel Fiott, defence expert at Belgium's Centre for Security, Diplomacy and Strategy, said the country's neutrality was born from the fact that it was a British military outpost and wanted to pull away from both Western and Soviet blocs. Its neutrality was constitutionally formalised 39 years ago.
Decades later, the definition has lost some of its rigidity and was publicly debated after Prime Minister Robert Abela backed the EU's €800 billion defence push 1 year ago. Around that time, Abela reportedly said the small island nation should reconsider how it traditionally interprets this status and that defence spending should increase to reflect the times.
For Malta, this means ensuring the security of subsea cables, maritime networks and cyber infrastructure, as it has a burgeoning gaming industry. According to the Times of Malta, the Mediterranean island has almost doubled its defence spending over a decade, from roughly €42 million in 2014 to €77 million in 2023. European Parliament data estimate a projected rise in defence spending to €100 million this year.
Abela said in early 2025: "We cannot adopt a position, as maybe we frequently have, that our country is cut off and completely protected from the realities around us."
The Coming Test
Politicians and defence officials have warned Russia could test NATO's defences by 2030. Everts said the real test of neutrality will come if Europe is confronted with armed aggression. "If there were a military attack on an EU member state, what then happens in terms of the reactions, in terms of the solidarity, in terms of the actual commitments, including in the military field of those four countries?" he asked. "That is when the question will truly be on the table."
Why This Matters:
The neutrality debate exposes a fundamental tension in European integration: member states retain sovereign control over defence policy, but mutual assistance obligations and shared security threats create expectations that constitutional neutrality may not accommodate. Austria's 2% GDP target, Ireland's €1.7 billion defence package, and Cyprus receiving €1.2 billion in EU defence funds show neutral states are increasing military spending — but whether they'll provide armed assistance to an attacked EU member remains constitutionally and politically unclear. The question isn't academic. With warnings of potential Russian aggression against NATO by 2030 and Cyprus already experiencing drone strikes, Europe's security architecture depends on knowing which states will fight and which will cite neutrality. For taxpayers in non-neutral states footing the bill for collective defence, the answer matters enormously.
