Russia's 2022 invasion of Ukraine was a defining moment for international law and its ability to maintain international peace and security. This book highlights the principles, methods and systems in place to regulate peaceful relations between states, and the implications the war in Ukraine has had on their relevance in the changing geopolitical world. Bringing together leading experts on international law, including key Ukrainian voices, the book explores the strengths and weaknesses in international law which have been exposed by Russia's invasion. The UN has stated that the war has catastrophic effects for international security and human rights. The book explores these statements, drawing on varied aspects of international law to determine lessons to be learned from the Ukraine conflict. It also explores how international law has had to adapt to tackle the challenges which have arisen. The book asks, has the conflict challenged the theory and fundamental values of international law? Have there been any new legal developments, prompted by the war, which could be applied to future conflicts? Through these timely questions, the book re-evaluates the changing landscape of international law. The book will be of interest to students and scholars in the fields of international law, the use of force, humanitarian law, criminal law, refugee law and human rights law.
