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 another state's territorial integrity or political independence, with narrow exceptions (self-defense against an armed attack, or UN Security Council authorization). Neither applied here—Ukraine had not attacked Russia, and there was no Security Council authorization.
The stated justifications don't hold up:
International response: The UN General Assembly voted overwhelmingly (141-5) to condemn the invasion as a violation of Ukrainian sovereignty. Most international legal scholars view it as a clear act of aggression.
Where reasonable debate exists:
The distinction matters: criticizing NATO expansion or Western foreign policy choices is different from justifying a war of aggression against a sovereign state. Most of the international community, including many countries not aligned with the West, has rejected the invasion as illegal.
