Abstract

This article argues that Ireland has become a critical vulnerability on Europe’s western flank as Russian military activity exposes gaps in Irish air, maritime, and undersea infrastructure security. Ireland’s limited naval and air capabilities, lack of military radar, and geographic position near major transatlantic sea lanes and undersea cables create risks not only for Ireland but also for NATO and the broader transatlantic security architecture. The author considers two options for strengthening Irish defense: NATO membership or Major Non-NATO Ally status with the United States. Major Non-NATO Ally status could improve Ireland’s access to U.S. equipment, technology, training, and bilateral security cooperation while preserving its traditional policy of nonalignment. NATO membership, however, would provide more immediate and enduring access to integrated air defense, fighter protection, maritime patrols, and capabilities for protecting critical undersea infrastructure. The author concludes that joining NATO is the most effective and urgent means of securing Ireland’s airspace and waters, strengthening the Western Atlantic, and reducing vulnerabilities that Russia could exploit.
