Reunification of Ireland: President Trump’s Recent Support for a Long-Term Irish Nationalist Project
President Donald Trump flew into Dublin Airport at around 8:20 am on 12 September 2026, in an early kickstart to a busy schedule of public engagements. The highlight of Trump’s two-day visit to the Republic of Ireland was his attendance at the Amgen Irish Open golf tournament, which was being held at the Trump International Golf Links in Doonbeg, County Clare. His trip was notable for his repeated declarations of support for the reunification of the island of Ireland, which received a cautious welcome from Irish nationalists but were unequivocally condemned by Unionists in Northern Ireland and by all mainstream political parties in Great Britain. Trump’s enthusiasm for a United Ireland may have also appealed to his not-inconsiderable voter base in America-where as many as 32.4 million Americans (almost one in ten of the population) claimed Irish ancestry in the 2024 census.
The entire island of Ireland joined Great Britain (England, Scotland, and Wales) to form the United Kingdom in 1801, following the 1800 Acts for the Union of Great Britain and Ireland. The union proved somewhat fragile, with growing demands for Irish ‘Home Rule’ under which Ireland would become a self-governing entity with its own parliament. Home Rule became a reality with the Government of Ireland Act 1920, which provided for devolved bicameral parliaments in Belfast and Dublin. The Anglo-Irish Treaty 1921 then created an Irish Free State in south, while Northern Ireland was excluded from its jurisdiction under the Irish Free State (Consequential Provisions Act) 1922. ‘Northern Ireland’ refers to the six northeastern counties which preferred to remain a dominion of the United Kingdom of Great Britain and Northern Ireland following partition. It must be noted, for the sake of completeness, that the northwestern corner of Ireland, including the island’s northernmost point at Malin Head, remained within the Republic of Ireland. Ireland was formally declared a republic by the Republic of Ireland Act 1949 and left the Commonwealth, while Northern Ireland retained its devolved status within the United Kingdom. Nationalists have continued ever since to seek reunification of Ireland as part of their political agenda.
An uneasy peace in Northern Ireland, which was marked by Protestant domination of the Catholic minority, transitioned into three decades of unremitting violence-the so-called ‘Troubles.’ Peace was eventually restored by the signing of the Good Friday Agreement (GFA) in Belfast on 10 April 1998. The GFA made provisions for future reunification by allowing the people of Ireland to exercise “their right of self-determination on the basis of consent, freely and concurrently given, North and South, to bring about a united Ireland.” This complements Article 3 of the Irish Constitution (Bunreacht na hÉireann), which provides for reunification “only by peaceful means with the consent of a majority of the people, democratically expressed, in both jurisdictions in the island.” The Northern Ireland Act 1998 states that “if at any time it appears likely to him that a majority of those voting would express a wish that Northern Ireland should cease to be a part of the United Kingdom and form part of a united Ireland, the Secretary of State shall make an Order in Council enabling a border poll.”
Existing legislation does not clarify how matters may be taken forwards if so required. Once it can be ascertained, by as yet undefined means, that a united Ireland is considered desirable, parallel votes on the issue will have to be held in both Northern Ireland and the Republic of Ireland. Some recent events suggest that reunification remains a distinct possibility. A majority (55.8%) of Northern Irish voters opted to retain EU membership during the 2016 Brexit referendum, in contrast with an overall UK vote of 48% in favour of Remain. The 2021 census conducted by the Northern Ireland Statistics and Research Agency (NSRA) found that people from a Catholic background accounted for 45.7% of the population, giving them a majority for the first time in the 101-year history of the province. In May 2022, Sinn Féin (We Ourselves) became the largest party in the Northern Ireland Assembly with 27 seats-the first nationalist party to achieve that distinction.
Considerable thought has been given to the desirability, or otherwise, of reunification of Ireland on economic, social, and political grounds. Nationalists claim that the cost of continued partition of the island is higher than that of reunification. Cynics claim that the Republic cannot afford to merge with Northern Ireland, which remains the poorest and most economically inactive region of the UK, with both low productivity and a large fiscal deficit- all despite an economy that is growing faster than the UK national average, albeit from a lower baseline. Northern Ireland currently benefits from subvention, whereby the UK Treasury allocates money to cover the shortfall between tax revenues raised locally and public sector spending in the province, thereby subsidising Northern Ireland to the tune of around £10 billion per year. Subvention may not, however, cover the entire fiscal deficit.
Economic convergence between the Republic of Ireland, with its stronger and faster-growing economy, and Northern Ireland is likely to incur challenges similar to those of German reunification, including the side-effects of harmonisation measures and fiscal transfers. Northern Ireland is currently the only region in the world that is able to freely trade goods with both EU and GB markets, through its unique ‘Dual-Market Access.’ Reuniting Ireland could further boost economic growth in Northern Ireland through the ability to benefit from EU regional development funds, and through improved incentives for foreign direct investment.
The UK government, however, considers Northern Ireland to be an integral part of the nation, and is keen to avoid breaking up the kingdom, especially when growing demands for Scottish and Welsh independence ominously lurk in the background. Furthermore, the Protestants of Northern Ireland, by and large, feel more British than Irish in terms of their cultural, political, and religious identity. This Protestant/Unionist/Loyalist community has been mostly defined by its Scots-Presbyterian and English-Anglican roots. While Trump might have articulated the desires of Irish nationalists, however inappropriately under the circumstances, it seems unlikely, given the balance of probabilities, that a united Ireland is imminent.
