Introduction: From a Long Hybrid War to a Full-Scale Assault

Russia’s 24 February 2022 onslaught did not erupt overnight. It crowned eight years of undeclared, “hybrid” hostilities launched with the seizure of Crimea in 2014 and rested on still deeper ideological, security, and regime-survival calculations in the Kremlin.

• Crimea and the birth of hybrid warfare (March 2014). Masked Russian troops in unmarked uniforms—nicknamed “little green men”—took over Ukrainian bases and parliament buildings, clearing the way for Moscow’s annexation of the peninsula after a lightning referendum that violated both Ukrainian law and multiple international agreements. APLWikipedia

More (2014-2021). While insisting it was not a party to the conflict, the Kremlin armed, financed, and often commanded separatist forces in the self-declared “people’s republics” of Donetsk and Luhansk, causing more than 14 000 battlefield deaths before 2022.
• Russia’s narrative of a “Western-backed coup.” Inside Russia, the Euromaidan revolution that toppled President Viktor Yanukovych in February 2014 is still framed as a U.S.-orchestrated coup—an enduring propagandaPropaganda is a form of communication aimed at influencing p...

• The Budapest Memorandum, 1994. When Kyiv surrendered the world’s third-largest nuclear arsenal, Moscow, Washington, and London pledged to “respect the independence and territorial integrity of Ukraine” and to refrain from the threat or use of force. Russia’s actions in 2014 and again in 2022 shattered those assurances, fueling today’s calls in Kyiv for binding security guarantees. Harvard Kennedy SchoolUnited Nations Treaty CollectionReuters

1 | Historical and Ideological Roots of Imperial Revisionism

In July 2021 Vladimir Putin published his essay “On the Historical Unity of Russians and Ukrainians,” denying Ukraine’s separate nationhood and depicting its modern borders as an historical mistake—an ideological lodestar for the coming invasion. Kremlin

2 | The Security Motive and the NATO Enlargement Dispute

The Kremlin portrayed the assault as a defensive move against hypothetical NATO expansion. In December 2021 it issued two draft treaties demanding a Ukrainian veto in NATO and a pull-back of allied forces to their 1997 lines—terms Western capitals rejected, viewing them as a pretext to restore a Russian sphere of influence rather than avert a real military threat. Wikipedia

3 | Revisionist Quest for a Sphere of Influence and Pushback Against the Liberal Order

Realist-leaning analyses stress Moscow’s bid to overturn the post-Cold-War status quo, rebuild a buffer zone, and dilute U.S. influence in Eastern Europe—part of a wider, authoritarian pushback against the liberal international order.

4 | Domestic Political Factors: Preventive and Diversionary Logic

Many scholars label the warWar (General Definition) War is a state of armed conflict be... More “preventive”: Putin feared Ukraine’s irreversible westward drift—and its democratic example—could destabilize his own autocratic rule. The invasion also served a diversionary purpose, rallying nationalist sentiment and distracting from economic stagnation and repression at home.

5 | Economic and Strategic Interests

Eastern Ukraine’s Donbas and the Black Sea coast contain rich coal, metal, and agricultural resources plus critical ports. By occupying parts of these regions, Russia seized about 12 percent of Ukraine’s territory—together with offshore gas fields formerly operated by state-owned Chornomornaftogaz on the Black Sea shelf. Atlantic Council

7 | Diplomatic Failure and Strategic Miscalculation

U.S.–Russia, NATO–Russia, and OSCE talks in January–February 2022 deadlocked on Moscow’s zero-enlargement demand. Putin’s circle expected Kyiv to fold within days and the West to splinter over sanctions—a fatal misreading of Ukrainian resilience and transatlantic unity.
