Is Russia's invasion of Ukraine justified?

The invasion's justifications are disputed under international law — I'll compile the legal findings and competing claims.

Russia's full-scale invasion of Ukraine, launched on 24 February 2022 as a "special military operation," is widely considered unjustified and illegal under international law, although Russia has offered its own legal and political justifications.

Russia's Stated Justifications

Russian President Vladimir Putin announced the operation as being to defend the Russian-speaking territories in eastern Ukraine — the Donetsk People's Republic and Luhansk People's Republic — under Article 51 of the United Nations Charter.

The stated reasons included claims that:

•Ukraine had been committing genocide against Russian speakers in the region
•Ukraine's government were neo-Nazis under Western control
•NATO was building up military infrastructure in Ukraine, threatening Russia
•Ukraine was developing nuclear weapons

Russia also argued that because it recognized the Donetsk and Luhansk People's Republics as independent states just before the invasion, its military action was a lawful request for assistance under Article 51, and invoked "historical injustices," including verbal assurances of NATO's non-expansion in the 1990s. It also framed the action as humanitarian intervention through accusations of "genocide".

International Legal Assessment

Under the UN Charter, the legal framework is:

•Article 2(4) states, "All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state"
•Article 51 provides for self-defense as the only justification for use of force against another country

Legal analyses have concluded:

•"There is no legal justification under Article 51 of the UN Charter for the military actions Russia has taken against Ukraine. There being no basis to claim self-defense, the actions by the Russian military represents an illegal aggression against the territorial integrity of Ukraine"
•"Under no scenario is Russia's armed invasion of Ukraine legal under contemporary international law and norms"
•Neither of the exceptions - self-defense from an armed attack or UN Security Council authorization - applied to Russia's invasion, as "Ukraine did not launch an armed attack against Russia, and the Security Council did not authorize any use of force", therefore it "represents a unilateral and illegal use of force"

Russia's response — annexation, recognition of breakaway entities, and large-scale conventional war — has been rejected as illegal aggression by the large majority of UN member states, the International Court of Justice, and the International Criminal Court.

Response of International Bodies

1.United Nations General Assembly: The General Assembly overwhelmingly condemned the invasion and called for Russian troops to immediately and completely withdraw. In the March 2, 2022 vote, 141 countries supported the resolution condemning Moscow and five were against it — including Russia, Belarus, Syria, North Korea and Eritrea. In a later vote, 141 out of 193 United Nations member states voted for the nonbinding resolution demanding Russia immediately withdraw.
2.International Court of Justice (ICJ): On 16 March 2022 the ICJ issued provisional orders that demand "the Russian Federation shall immediately suspend the military operations that it commenced on 24 February 2022 in the territory of Ukraine". The Court prima facie rejected the argument that because Russia was basing its use of force on self-defense under article 51 the Court had no jurisdiction.

The ICJ also "stated that there was no evidence to support Russia's claim that Ukraine was committing genocide in the eastern regions of the country", and "no credible international organization or observer, including the United Nations or independent human rights monitors, found any...evidence of genocide in Ukraine". The Court found no substantiation for Russia's genocide claims.

Summary

From the perspective of international law as interpreted by the UN, the ICJ, and the majority of states, the invasion lacks legal justification because Ukraine did not attack Russia and therefore a claim of self-defense under Article 51 does not apply. From Russia's perspective, the action is justified as collective self-defense of the Donbas republics, prevention of genocide, denazification, and protection against NATO expansion. The international community's legal bodies have rejected those justifications as factually unsubstantiated and legally insufficient.
