The question of whether Russia's invasion of Ukraine is justified is a central point of division in global politics. The Russian government has presented several arguments to justify its military actions, while Ukraine, the United Nations, and the vast majority of the international community have rejected these claims, viewing the invasion as an unprovoked and illegal act of aggression.
Here is an overview of the primary arguments from both perspectives.
The Arguments Presented by the Russian Government
The Russian leadership, led by President Vladimir Putin, has articulated several justifications for what it terms a "special military operation":
1.Opposition to NATO Expansion: Russia argues that the eastward expansion of the North Atlantic Treaty Organization (NATO) poses an existential threat to its national security. Moscow contends that Western powers reneged on verbal promises made at the end of the Cold War not to expand NATO toward Russian borders. Russia views the prospect of Ukraine joining NATO as a "red line" that would place hostile military infrastructure directly on its border.
2.Protection of Russian-Speaking Populations: The Russian government claims that its intervention was necessary to protect Russian-speaking populations in the Donbas region of eastern Ukraine. Moscow accused the Ukrainian government of discrimination, shelling civilian areas, and committing "genocide" against Russian speakers following the 2014 Maidan revolution, which ousted Ukraine’s pro-Russian president, Viktor Yanukovych.
3."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 (such as the Azov Regiment) and posed a threat to Russia and Russian-aligned communities.
4.Historical and Cultural Claims: President Putin has frequently argued that Russians and Ukrainians are "one people" sharing a single historical and spiritual space. From this perspective, the modern Ukrainian state is viewed as an artificial construct created on historically Russian lands, and its alignment with the West is seen as an unnatural separation.
The Arguments of Ukraine, the United Nations, and the International Community
The overwhelming majority of countries, international legal bodies, and historians reject Russia’s justifications, presenting the following counterarguments:
1.Violation of International Law and Sovereignty: Ukraine and its international allies point out that the invasion is a direct violation of Article 2(4) of the United Nations Charter, which prohibits the threat or use of force against the territorial integrity or political independence of any state. Under international law, Russia's actions are classified as an illegal war of aggression.
2.The Right to Self-Determination: Proponents of Ukraine’s sovereignty argue that as an independent, internationally recognized nation, Ukraine has the sovereign right to determine its own foreign policy, including seeking membership in alliances like NATO or the European Union. They emphasize that Russia formally recognized Ukraine's borders—including Crimea and the Donbas—in the 1991 Belovezha Accords and the 1994 Budapest Memorandum, in which Russia pledged to respect Ukraine's independence and existing borders in exchange for Ukraine giving up its nuclear arsenal.
3.Rejection of "Genocide" and "Nazism" Claims: Independent international bodies, including the United Nations and the International Court of Justice (ICJ), have found no evidence to support Russia’s claims of "genocide" against Russian speakers in Ukraine. In March 2022, the ICJ ordered Russia to immediately suspend its military operations, noting the lack of evidence for the allegations. Furthermore, observers point out that 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 far-right parties failed to win any seats in the Ukrainian parliament in the most recent democratic elections.
4.Defensive Nature of NATO: NATO and Western nations maintain that NATO is a purely defensive alliance that poses no threat to Russia. They argue that countries join NATO voluntarily to protect themselves from external aggression, a concern that they argue has been validated by Russia's military interventions in Georgia (2008) and Ukraine (2014 and 2022).
5.Global Consensus: The United Nations General Assembly has repeatedly passed resolutions by overwhelming majorities (such as Resolution ES-11/1) condemning the invasion, demanding the immediate and unconditional withdrawal of Russian forces, and declaring Russia’s attempted annexations of Ukrainian territories (Crimea, Donetsk, Luhansk, Zaporizhzhia, and Kherson) illegal under international law.
