Russia’s aggression against Ukraine is a violation of international law, and the country´s conduct during hostilities has raised concern. This triggers questions about the international legal order itself, but also Russia’s relations to international law in general, and to international humanitarian law in particular. Is international law universal or are there various versions of it? What is Russia’s take on international law? What ideas does Russia connect to international law and how does it use them? How does it see international humanitarian law today? How does Russia’s perspective of international law affect management of global problems and relations to international institutions?
