Abstract
Ireland plays a crucial role in protecting Europe’s western flank, but growing Russian aggression has exposed serious gaps in its security. With a small, outdated naval fleet, limited air capabilities, and inadequate radar systems, Ireland struggles to defend its airspace, waters, and critical undersea cables—vital infrastructure that carries 97% of transatlantic data and underpins global communication and security. These vulnerabilities have made Ireland a target for Russian sabotage and incursions, posing risks to Europe and the transatlantic alliance.
The article explores two paths for Ireland to address these security challenges: joining NATO or seeking Major Non-NATO Ally (MNNA) status with the United States. NATO membership would provide immediate access to collective defense systems, such as advanced air and missile defense, maritime patrols, and infrastructure protection, significantly boosting Ireland’s ability to deter threats. Alternatively, MNNA status would allow Ireland to strengthen its defenses through a bilateral agreement with the U.S. while maintaining its policy of neutrality.
The author argues that joining NATO is Ireland’s most effective and urgent option. Membership would bolster Europe’s Atlantic defenses, secure critical infrastructure, and elevate Ireland’s role as an active contributor to European and transatlantic security, ensuring its safety in an increasingly volatile geopolitical landscape.
