UN organs play a significant role in implementing the law of State responsibility in global security contexts. This book analyses how the ICJ, the General Assembly and the Security Council contribute to the implementation of the laws of State responsibility, using transnational terrorism as its principal case study. Some books deserve to be read and then re-read. Vincent-Joël Proulx's monograph is a comprehensive exploration of the relationship between the law of state responsibility and the institutional framework of the Charter of the United Nations (UN Charter) as it relates to collective security.
