Security and Defense Policy in a
Reunited Ireland
Abstract:
Ireland faces an urgent need to reassess its defense policy and
rapidly strengthen military capabilities in response to a more
contested European security environment and Russian aggression in
Ukraine. Its strategic maritime position, vital communications
infrastructure, and limited current force posture make the country
vulnerable to coercion, hybrid attacks, and disruption of essential
national services. Without a firm commitment to increased defense
spending, modernization of capabilities, and closer operational
collaboration with European partners, Ireland will find it difficult
to deter or defend against high-end threats effectively.
Ireland's strategic vulnerability:
It’s time for Ireland to realize that it is essentially a sitting
duck in a rapidly evolving world. Rogue world leaders and ruthless
dictators are abandoning democracies, strategic military alliances,
and all political and diplomatic norms in favor of a new world order
led by autocrats and oligarchs. Whatever reasons Ireland may have
had for its stance in the past are now irrelevant. This situation
also puts Ireland in the sights of malicious actors like Russia
because of its strategic location on major transatlantic sea, air,
and communications cable routes between North America and northern
Europe.
Underutilization of national potential:
In an ideal world, Ireland
would stand ready for any contingency. Endowed with nature’s finest
gifts, a strategic location, temperate climate, fertile soil,
abundant freshwater, resilient coastlines, and landscapes of
breathtaking beauty, this island possesses all the raw ingredients
for a secure and flourishing society. Yet paradise remains
unfinished.
Despite its manageable population, world-class education system, and deep
cultural reserves, Ireland lags behind its peers in self-reliance
and innovation. It has birthed some of the world’s most brilliant
minds, and continues to do so, yet fails to harness that talent to
build a society worthy of its promise. While other nations reap the
benefits of Irish ingenuity, our own institutions remain hesitant,
fragmented, and reactive. This is not a failure of nature. It is a
failure of vision.
Economic overreliance on multinationals:
For decades, Ireland has outsourced complexity, entrusting
multinationals with its economic engine and depending on external
powers to navigate global turbulence. This dependency has fostered
complacency. As the established world order fractures, disrupting
trade agreements, military alliances, and cybersecurity norms,
Ireland finds itself exposed and unprepared to chart its own course.
The United States, once a steadfast benefactor, now views Ireland’s trade
advantages with suspicion. What was once considered a partnership is
now seen as exploitation. Favorable tax policies and open-market
strategies, long the foundation of Ireland’s prosperity, risk being
labeled as unfair trade practices. Retaliation is a possibility.
Ireland’s fifty-year stability, rooted in transatlantic goodwill, is no
longer assured. In this moment of disruption, the issue is not just
economic; it's constitutional. Can Ireland redefine its sovereignty,
adjust its dependencies, and build resilience from within?
Ireland’s economic vulnerability is no longer hypothetical: it’s
structural. In the short term, no fiscal maneuver can offset the
damage that would result from U.S. tariffs or the repatriation of
profits by American multinationals. The deeper issue lies in
Ireland’s over-reliance on corporate tax revenue from these firms to
fund its social welfare budget. This is a high-risk strategy, one
that falters in the face of global downturns or geopolitical
rupture.
Should the U.S. government follow through on its threats, Ireland will
likely be forced to borrow to sustain basic social protections. In a
more resilient model, windfall tax revenue from multinationals would
be channeled into infrastructure and rainy-day reserves,
expenditures that can be paused during a crisis. But that’s not how
the Irish state has chosen to operate. Instead, it has tethered its
social contract to the fortunes of foreign capital.
Risks of a U.S. withdrawal
from NATO:
The North Atlantic Treaty Organization’s (NATO) security umbrella,
which has protected Europe and Ireland since the end of World War
II, may be abandoned by the U.S., leaving Europe, including Ireland,
vulnerable to Russian expansionism. Ireland, which is not a NATO
member, is still protected due to its strategic location. Similar to
the trade situation, Ireland’s only security option is to align with
Europe and hope for the best.
Insufficient Defense Spending:
In 2022, Ireland's defense budget was $1.16 billion, roughly 0.23%
of its GDP. That same year, the U.S. spent $776.94 billion on
defense, which is 3.45% of its GDP. England spent $68.46 billion,
which is equal to 2.23% of its GDP. For 2025, Ireland’s defense
budget is planned at $1.49 billion, about 1.4% of its GDP. According
to Irish government reports, this is in line with the defense
budgets of other small European countries.
These minuscule increases in the
defense budget will not be sufficient to persuade other European
countries to defend Ireland if it is attacked or threatened by
Russia or another hostile actor. If the U.S. follows through on its
threat to withdraw from NATO, Ireland must be prepared to deploy
troops as part of Europe's Coalition of the Willing, a military
alliance; otherwise, it will have to defend itself alone.
Limited military role and recent policy changes:
Currently, Ireland's Defense Force has about 8,500 personnel in the
Army, Air Corps, and Naval Service. Realistically, protecting its
territory and security in a world filled with aggressive
superpowers, unstable autocrats, and land grabbers would require
more than two brigades and a defense budget of $1.49 billion.
Defending a country surrounded by oceans and 4,677 miles of
coastline with such a small military force is impractical to do
alone.
Ireland’s military role globally has primarily been limited to
peacekeeping missions under United Nations (UN) mandates. It lacks
combat experience because a so-called triple lock system restricts
it. Recently, U.S. policy shifts away from supporting Ukraine and
the potential U.S. withdrawal from NATO have led Ireland to
recognize its lack of an effective military deterrence capability.
To address this, the government increased its defense budget and
abolished the triple lock system, allowing the deployment of
peacekeepers without requiring UN approval.
Need for European defense integration:
Now that the reality of Russian
expansionism and American retrenchment has sunk in,
Ireland, along with other European countries, must dramatically
accelerate the development of its military capabilities to ensure
European self-reliance in the face of further Russian aggression.
The ongoing Russian war of aggression in Ukraine and the impacts of
the recent United States elections have placed Ireland in a position
that requires a serious reassessment of its role in Europe and what
it must do to defend itself.
Ireland’s tradition of neutrality must now shift toward a commitment
to collective European resilience.
Minor tweaks to its security
system while remaining on the sidelines won’t protect it from an
aggressive Russia. Only a strong commitment to a European defense
alliance will do. Standing by while the rest of Europe bleeds is
unacceptable: like watching others walk into a minefield, hoping the
blast won’t reach its doorstep. Only through a united European
defense can Ireland protect not just its borders, but the democratic
values that unite its people.
