Whether Russia’s invasion of Ukraine is justified is a highly contested question with starkly different answers depending on the perspective of the Russian government, the Ukrainian government, and the international community.
Under international law and the consensus of the vast majority of nations, the invasion is considered an unprovoked and illegal act of aggression. However, the Russian government has presented its own set of justifications.
Below is an overview of the primary arguments and perspectives surrounding the conflict.
1. The Russian Government's Justifications
The Russian leadership, led by President Vladimir Putin, has put forward several arguments to justify what it officially terms a "special military operation":
•Security Concerns regarding NATO Expansion: Russia argues that the eastward expansion of NATO—specifically the prospect of Ukraine joining the military alliance—poses an existential threat to Russian national security. Moscow contends that Western powers broke promises made at the end of the Cold War regarding NATO's expansion and argues that Ukraine's potential integration into Western security structures violates the principle of "indivisible security" (the idea that one country should not strengthen its security at the expense of another's).
•Protection of Russian Speakers in Donbas: Moscow claims that the invasion was necessary to protect Russian-speaking populations in the eastern Ukrainian region of Donbas. The Russian government alleged that these populations were facing persecution, discrimination, and "genocide" by the Ukrainian government following the 2014 Euromaidan protests, which ousted Ukraine's pro-Russian president, Viktor Yanukovych.
•"Demilitarization and Denazification": Russia stated that its goals included the "demilitarization" and "denazification" of Ukraine. It claimed that far-right and neo-Nazi elements had seized significant influence within the Ukrainian government and military, posing a threat to Russia and to Ukrainian citizens.
•Historical and Cultural Ties: President Putin has frequently argued that Russians and Ukrainians are "one people" and has questioned the historical legitimacy of Ukraine's borders, claiming that modern Ukraine was created on historically Russian lands.
2. Ukraine's Perspective
Ukraine and its citizens overwhelmingly reject Russia's justifications, viewing the invasion as a violent, imperialist assault on their existence as an independent nation:
•Sovereignty and Self-Determination: Ukraine is a sovereign, independent state recognized by the United Nations (including Russia, which signed the 1994 Budapest Memorandum promising to respect Ukraine's independence and existing borders). Ukraine asserts its sovereign right to determine its own foreign policy, domestic laws, and international alliances, including its aspiration to join NATO and the European Union, free from foreign coercion.
•Rejection of "Genocide" and "Nazism" Claims: Ukraine and independent international observers have roundly dismissed Russia's claims of "genocide" against Russian speakers as false propaganda. While far-right groups exist in Ukraine (as they do in many countries), they hold negligible political power; Ukraine’s president, Volodymyr Zelenskyy, is Jewish, and the far-right coalition failed to win any seats in the parliament in the most recent democratic elections.
•Defense Against Existential Threat: Ukraine views the invasion as an unprovoked war of conquest aimed at erasing Ukrainian national identity, overthrowing its democratically elected government, and annexing its territory.
3. The International Community and International Law
The overwhelming consensus among international legal bodies, global organizations, and the vast majority of the world's governments is that Russia's invasion of Ukraine is entirely unjustified and illegal.
•Violation of the UN Charter: The United Nations General Assembly has repeatedly voted by an overwhelming majority to condemn the invasion. The UN Charter (specifically Article 2, Paragraph 4) strictly prohibits the threat or use of force against the territorial integrity or political independence of any state. The invasion is widely categorized under international law as a "crime of aggression."
•The Budapest Memorandum: In 1994, Ukraine agreed to give up the world's third-largest nuclear arsenal (which it inherited after the fall of the Soviet Union) in exchange for security assurances. Russia, the United States, and the United Kingdom signed the Budapest Memorandum, committing to respect Ukraine's independence, sovereignty, and existing borders, and to refrain from the threat or use of force against it.
•Rulings by International Courts:
•In March 2022, the International Court of Justice (ICJ)—the principal judicial organ of the UN—ordered Russia to immediately suspend its military operations in Ukraine, rejecting Russia's legal justification that it was preventing a "genocide" in Donbas.
•The International Criminal Court (ICC) has issued arrest warrants for Russian officials, including President Vladimir Putin, for war crimes related to the unlawful deportation and transfer of children from Ukraine to Russia.
•Global Sanctions and Support: The United States, the European Union, the United Kingdom, Canada, Japan, and numerous other nations have imposed unprecedented economic sanctions on Russia and provided military, financial, and humanitarian aid to Ukraine to help it defend itself.
Summary
While the Russian government justifies its military actions as a preemptive defense against NATO expansion, a protection of Russian-speaking minorities, and an assertion of historical rights, these arguments are rejected by Ukraine and the international community. Under international law, the invasion is overwhelmingly viewed as an unlawful, unprovoked violation of a sovereign state's territorial integrity.
