Is Russia's invasion of Ukraine justified?
No
Short answer: No. Under international law, Russia’s full‑scale invasion of Ukraine on February 24, 2022 is widely considered unlawful and unjustified.
Why:
•The UN Charter forbids the use of force against another state’s territorial integrity or political independence (Article 2(4)). The only clear exceptions are UN Security Council authorization or self‑defense against an armed attack (Article 51). Russia had neither.
•Claims of self‑defense or “preemptive” defense require evidence of an imminent armed attack by Ukraine; none has been demonstrated. NATO expansion or political disagreements don’t meet the legal threshold for self‑defense.
•Assertions of protecting people in Donbas or preventing “genocide” have not been accepted by major international bodies; the International Court of Justice ordered Russia on March 16, 2022 to suspend military operations in Ukraine, finding no plausible basis for that justification at that stage.
•Multiple UN General Assembly resolutions in 2022–2023 condemned the invasion and subsequent annexation claims as violations of international law and the UN Charter.
Moral frames (just‑war theory) point the same way: no just cause, not a last resort, and grossly disproportionate harm to civilians.
If you’d like, I can share key documents (UN Charter provisions, the ICJ order, UNGA vote tallies) or walk through Russia’s stated arguments and why most legal scholars reject them.
