Tánaiste and Minister for Defence Simon Harris said the alliance would “safeguard [Ireland’s] maritime domain”

The Irish government has said membership of a European maritime alliance will not undermine the county’s neutrality.

The Tánaiste and Minister for Defence Simon Harris has given the Irish Defence Forces approval to formally join the Common Information Sharing Environment (CISE).

The government said CISE enables more effective operations at sea amid new and evolving maritime threats.

As part of the network, the Irish Naval Service can exchange and share information with military and civilian maritime authorities in 10 other European countries.

The Irish government said CISE plays a crucial role in increasing awareness of maritime activities and improving responses to growing threats at sea, including physical and cyber-attacks on critical infrastructure, drug trafficking and other illegal activities.

Ireland is joining the group at a time when the country is also establishing its first national maritime security strategy.

Harris said: “I am confident that there are considerable benefits from participation in this important initiative, which is a key enabler for our Maritime Security Strategy, helping to safeguard our maritime domain, boost our resilience and helping us to contribute with partners at an EU level.”

Neutrality is ‘best defence’

Donnchadh Ó Laoghaire says Ireland’s neutrality is its “best defence”

Ireland’s main opposition party, Sinn Féin, has raised concerns about the decision.

The party’s defence spokesperson, the TD (Teachta Dála) Donnchadh Ó Laoghaire, said, the minister “must ensure that this sharing of information does not impact in any way on Ireland’s neutrality.”

Mr Ó’Laoghaire has also said that the matter has not had “the constitutionally and legally bare minimum level of scrutiny or even oversight from the Oireachtas (Irish Parliament)”.

He added: “I will be requesting that the Oireachtas Committee on Defence call on the Tánaiste to attend a meeting in order to outline the details of this arrangement and similar arrangements, and to address concerns that such arrangements are further eroding Irish neutrality.

“Irish neutrality allows Ireland to play a positive and constructive role in global affairs, it is our best defence.”

‘Not about joining a military alliance’

Harris has insisted that the decision does not undermine Irish neutrality.

He said it’s a voluntary information sharing arrangement and is not about joining “any sort of military alliance”.

The CISE network is overseen by the European Commission with the aim of sharing information around a range of issues such as maritime safety and security, border control, the marine environment, fisheries control, trade, economic interests, and law enforcement and defence.

The decision of the Irish Defence Forces to join the group comes at a time of increasing awareness in the country about potential threats to critical infrastructure including transatlantic communication cables and pipelines along the seabed off the Irish coast.

Ireland’s small naval patrol fleet

There are concerns about the potential risk of sabotage by hostile states or international criminals.

The challenges have been exacerbated by what many observers now regard as persistent problems around the operation of Ireland’s small naval patrol fleet as well as difficulties around the recruitment of personnel into the navy.

The new Irish government says improvements to maritime surveillance is now “a national defence policy priority”.
