Protests erupt in Ireland over plan to end military neutrality

Ireland is witnessing major demonstrations against the effective abolition of the country’s long-standing neutrality, driven by a plan for militarization within the EU framework.

On Saturday, approximately one thousand people took to the streets of Dublin to protest the government’s plan to dismantle the “Triple Lock” system. The Triple Lock is a constitutional mechanism requiring that any mission involving twelve or more Irish soldiers must be approved by a UN Security Council or UN General Assembly resolution. This provision is intended to help preserve the country’s historic neutrality, which is deeply rooted in its history under British colonial rule.

Anthony Coughlan, an emeritus professor at Trinity College Dublin and spokesperson for the National Platform EU Research and Information Centre, told German Foreign Policy that refusing to participate in foreign wars, especially alongside the United Kingdom, is “a fundamental element of the national sentiment of the Irish people.” The government’s attempt to break with the tradition of neutrality by abolishing the Triple Lock is seen partly as a consequence of Irish leaders’ integration into EU institutions.

The de facto breach of neutrality: UN charter requirement removed

The Irish government is preparing to abolish the Triple Lock system to allow for greater flexibility in the future deployment of Irish soldiers. To this end, it has introduced a draft bill called the Defence (Amendment) Bill 2025. The bill’s core provision is that the deployment of Irish soldiers abroad can be done without the approval of the UN Security Council.

As a concession, the bill states that deployments must simply be conducted in accordance with the principles of the United Nations Charter. The aim here is to open up a broad and flexible range of military actions by facilitating missions for peacekeeping, conflict prevention, and “strengthening international security.”

Future missions involving more than fifty Irish soldiers will still normally require not only a government decision but also a parliamentary resolution in the Dáil. However, this latter requirement can be waived if the mission is extended, as the government has discretionary power in this matter. Furthermore, missions involving fewer than fifty Irish soldiers will no longer be subject to parliamentary approval. Indeed, sending troops will not be limited to the UN; it will also be possible within the framework of the OSCE, the EU, and any other regional organizations, provided it is deemed consistent with the UN Charter and international law. NATO also claims to be a compatible organization in this regard.

Growing backlash against the erosion of neutrality

Opposition to the abolition of Ireland’s Triple Lock system is steadily growing. Last Saturday, around one thousand people demonstrated in Dublin against the removal of legal restrictions on military interventions and for the preservation of Irish neutrality. The protest was organized by a broad alliance of opposition parties, including Sinn Féin, and non-parliamentary organizations campaigning together under the slogan “United for Neutrality.”

Speakers included Alice-Mary Higgins, an independent senator in the Irish Senate (Seanad Éireann), and Mary Lou McDonald, the president of Sinn Féin. In May, opposition politicians declared they would “fight to the end” to protect the country’s constitutional neutrality and the Triple Lock. Protesters on the streets chanted slogans such as, “Protect our neutrality!” and “Save our Triple Lock!”

Irish neutrality: A rejection of British colonialism

According to the Irish Neutrality League, Ireland’s neutrality means that the Irish state “adopts the principle of impartiality by refraining from providing support or assistance to any of the parties in a military conflict, thereby reducing the likelihood of prolonging or escalating the war.”

Historically, Ireland’s neutrality is rooted in its experience under British colonial rule. The Irish Neutrality League argues that as a “post-colonial nation,” Ireland suffered under “imperialist conquest and occupation” and has no moral inclination to do the same to other countries. Coughlan asserts that opposition to wars in distant lands and membership in military alliances is “a fundamental element of the national sentiment of the Irish people,” adding, “There is very little desire to join wars shoulder-to-shoulder with Britain.”

Polls show a high level of support for neutrality. Most recently, a survey conducted by The Irish Times in April 2025 found that nearly two-thirds of respondents favored neutrality.

Ireland’s contradiction as an EU member

There is a direct contradiction between Ireland’s neutrality as an EU member state and the EU’s own stance. This conflict has existed since the EU signed the European Security and Defence Policy (ESDP). A common military policy was established with the Treaty of Nice, signed in 2001 and effective from January 1, 2003.

This contradiction is seen as the main reason the Irish people initially rejected the treaty in a referendum. The public approved the treaty in a second referendum only after the government accepted the “Triple Lock” safeguard. According to this arrangement, the deployment of more than twelve Irish soldiers abroad is not possible without, firstly, government approval; secondly, the consent of the Irish parliament; and thirdly, a supporting resolution from the United Nations Security Council or General Assembly.

The problem of public resistance to EU militarization was repeated with the Treaty of Lisbon, signed in 2007, which only came into force on December 1, 2009. This treaty provided for the transformation of the ESDP into the more comprehensive Common Security and Defence Policy (CSDP). It was also initially rejected in a referendum but was approved in a second Irish referendum after the government reaffirmed the role of the Triple Lock.

Stealth militarization: The state disregards the public

The Irish government has, in practice, undermined the country’s constitutional neutrality on numerous occasions. For example, Dublin has allowed US military transport planes to stop over at Shannon Airport on their way to war zones in the Middle East.

As Coughlan points out, Ireland also plays an active role in the EU’s foreign and military policy. On October 1, 2024, Micheál Martin, who was then Deputy Prime Minister (Tánaiste) and Minister for Defence before becoming Prime Minister (Taoiseach), officially acknowledged that Dublin was considering joining the European Sky Shield Initiative (ESSI), an air defense system initiated by Germany but covering all of Europe.

Prior to this, in February 2024, the Irish government signed the Individually Tailored Partnership Programme (ITPP) with NATO, which allows for greater information exchange, including intelligence. A member of the Irish government confirmed at the time that Ireland had access to NATO’s cyber defense systems, for example. Ireland is a “contributing participant” in the NATO Cooperative Cyber Defence Centre of Excellence (NATO CCDCOE) located in Tallinn, Estonia. Dublin also argues that NATO cooperation helps protect Ireland’s own underwater infrastructure.
