The Defence Forces are expanding towards a planned strength of 11,500 personnel by 2028, and an increasing proportion of new recruits were born outside Ireland.

According to reported figures, between 13% and 18% of recruits since 2022 have been born outside the Irish State.
That statistic deserves discussion, but we need to ask the right question.
Being foreign-born does not make somebody a security threat. Many foreign-born people have lived in Ireland for years, have built their lives here and subsequently become Irish citizens. Others eligible to join include EEA nationals, recognised refugees and people with subsidiary protection who meet residency and other requirements.

The real national-security issue is therefore not someone’s place of birth. It is how Ireland vets military personnel and decides who gets access to our most sensitive capabilities.
Every Defence Forces applicant undergoes security vetting. The Department of Defence has confirmed that this is carried out with the assistance of An Garda Síochána and that cases involving an overseas or non-national component can require contact with international vetting authorities.

That is reassuring. But as Ireland invests heavily in defence, cyber capabilities, intelligence, radar, communications, weapons systems and maritime security, another question arises; should every person who can join the Defence Forces automatically be eligible for every sensitive military appointment?

Other democracies make an important distinction between being eligible to serve and being eligible to access highly classified information.
The United States allows lawful permanent residents to enlist, but non-US citizens generally cannot obtain a personnel security clearance. That restricts access to classified information and certain sensitive military occupations.

The United Kingdom also recruits some non-UK nationals but operates several levels of national-security vetting. Higher-level vetting can examine overseas connections, financial circumstances, family relationships and other vulnerabilities relevant to foreign influence or coercion. Some particularly sensitive national-security and intelligence positions may also be restricted by nationality.

Canada permits permanent residents to serve in its armed forces, but its security system is similarly graduated. Under recent reforms, Canadian citizenship is required for Top Secret and Enhanced Top Secret clearance, alongside stronger continuing security checks.

So what is Ireland’s equivalent?
That is the question I believe deserves a clear public answer.
Ireland should be able to welcome people who genuinely wish to serve their adopted country, while simultaneously protecting intelligence, cyber systems, strategic communications, weapons and other sensitive military capabilities. Those two objectives are not contradictory.
A modern security system should assess the individual, not stereotype somebody according to birthplace. But it should also recognise that foreign intelligence services seek leverage through relationships, financial pressure, overseas connections, coercion and access to information. And those risks can apply to Irish-born personnel too.

Perhaps Ireland therefore needs a more clearly defined system in which eligibility to join the Defence Forces; eligibility to receive particular security clearances; and eligibility to work in the most sensitive areas of intelligence, cyber, communications and strategic defenceare treated as separate questions.

There may already be classified safeguards that cannot sensibly be made public. But the Government should at least be able to explain the principles governing the system.
With the Defence Forces expanding rapidly and Ireland facing a much more complicated international security environment, this is not a question about ethnicity or immigration. It is a question about national security, loyalty, vetting and access to sensitive information.
Ireland should welcome anyone who is eligible and genuinely committed to serving the Irish State. But the State also has a duty to ensure that whoever gets access to its most sensitive military capabilities, Irish-born or foreign-born, has been vetted to a standard appropriate to that responsibility.

As we expand our Defence Forces, perhaps the question we should be asking is; “Do Ireland’s security-clearance rules match the military we are now trying to build?”
