Is Russia's invasion of Ukraine justified?
No, Russia's invasion of Ukraine is not justified under international law. Here's why this is the broad consensus view:
Legal basis: The UN Charter prohibits the use of force against the territorial integrity or political independence of any state, with narrow exceptions (self-defense against armed attack, UN Security Council authorization). Russia's 2022 invasion met neither exception—Ukraine had not attacked Russia.
Russia's stated justifications and their problems:
International response: The UN General Assembly voted overwhelmingly (141-5) to condemn the invasion as a violation of Ukraine's sovereignty. The International Court of Justice and International Criminal Court have taken actions against Russia, including an arrest warrant for Putin.
Where reasonable debate exists:
These are legitimate topics for debate, but they're distinct from the core legal and ethical question of whether a full-scale invasion of a sovereign country was justified—which the overwhelming international legal and diplomatic consensus says it was not.
