The Impact of the Iranian Issue on Euro-Atlantic Security

Abstract

The Middle East, as a major geopolitical and economic player, exerts a critical influence on Euro-Atlantic security. In the context of political instability and ongoing conflicts in the region, the Russia-Ukraine war, and energy security challenges, the impact of Iran, as one of the region's dominant powers, on Euro-Atlantic security is of particular interest.

Iran’s geopolitical position, its nuclear ambitions, regional influence, and increasingly complex relations with major international actors play a significant role in shaping the security dynamics of the Euro-Atlantic space. In June 2025, amid escalating tensions in the region, the importance of the Iranian issue for the security of NATO member states became evident.

The article examines the main components of Iran’s foreign, regional, and domestic policies through which the regime established after 1979 is attempting to expand its influence. Particular attention is given to the impact of each component on Euro-Atlantic security. The study concludes by analyzing the impact each component of Iran’s policy has and/or may have on Euro-Atlantic security.
