It seems there might be confusion in the query as there isn't a prominent organization specifically named "European Leaders." However, I'll provide a summary about the **European Leadership Network (ELN)**, which is a notable organization related to European leadership in security and foreign policy. ## European Leadership Network (ELN) The European Leadership Network (ELN) is a pan-European think-tank focused on European foreign, defense, and security issues. Founded in 2011, it aims to build better security for a wider Europe by addressing the gravest risks to European security through research, publications, and policy advocacy[1][2]. ### History and Objectives The ELN was initially part of the Nuclear Security Project, aiming to create a dialogue on nuclear disarmament. Over time, its scope expanded to address broader European security challenges, including the loss of cohesion among states, unintended war risks, and new military technologies[1][2]. ### Key Achievements - **Nuclear Security**: The ELN's work has been recognized with prestigious awards, such as the Nunn-Lugar Award for Promoting Nuclear Security, received by former UK Defence Secretary Des Browne and former Russian Foreign Minister Igor Ivanov[2]. - **Policy Impact**: The ELN influences European security policy through its networks of leaders and partnerships across Europe and beyond[1][2]. ### Current Status As of 2025, the ELN was declared an undesirable organization in Russia, reflecting its impactful role in European security discussions[2]. Despite this, the ELN continues to engage with European leaders on critical security issues. ### Notable Aspects - **Networking**: The ELN's strength lies in its network of over 450 current, past, and future European leaders across various sectors[1]. - **Global Partnerships**: The ELN collaborates with institutions in North America, Latin America, and the Asia-Pacific region, enhancing its global influence[1].
