Understanding Russia’s Invasion and Ongoing War in Ukraine

Russia’s unprovoked invasion of Ukraine in February 2022 shocked the world. This full-scale military invasion ordered by Russian President Vladimir Putin has resulted in a devastating war in Ukraine that is still ongoing. As the conflict continues to evolve, many are struggling to fully comprehend Russia’s motivations, aims, tactics and the implications of this war. This comprehensive guide provides an in-depth analysis of the background, causes, timeline, military strategies, global response and potential outcomes to Russia’s invasion of Ukraine.

Background and Historical Context

To fully grasp this conflict, it’s important to understand the intertwined history of Russia and Ukraine dating back centuries. Key factors providing context include:

  • Shared Slavic roots and culture: Russians and Ukrainians share ethnic, linguistic and cultural bonds. But Ukraine has developed a distinct national identity since independence in 1991.
  • Political and military dominance: Ukraine was part of the Russian Empire for centuries, then part of the Soviet Union. Russia views Ukraine as part of its sphere of influence.
  • Territory and resources: Ukraine offers strategic advantages including natural gas pipelines, farmland, mineral resources and access to the Black Sea.
  • 2014 annexation of Crimea: Russia already annexed Ukraine’s Crimean Peninsula in 2014, citing historical ties and pro-Russian population.
  • Separatist-controlled regions: Pro-Russian separatists took control of the eastern Donbas region in Ukraine after 2014, with Russia’s support.

This complex backdrop helped shape the escalating tensions leading up to Russia’s 2022 invasion.

Key Causes and Triggers of Russia’s Invasion

Russia’s decision to launch a full invasion stemmed from multiple overlapping factors and triggers:

  • Putin’s historical and nationalist ambitions to rebuild greater Russia and reassert dominance over former Soviet states.
  • Perceived threat of NATO expansion into Ukraine, bringing Western military alliance closer to Russian borders.
  • Rejection of growing Western ties and democracy in Ukraine which Putin saw as undermining Russian influence.
  • Ukraine’s increased alignment with the West – aspirations to join the EU and NATO angered the Kremlin.
  • Unresolved status of separatist-held regions – Putin recognized their independence just before invading.
  • Disputed idea of “denazification” – false Kremlin narrative of threat posed by Ukrainian nationalism and leadership.
  • Domestic political factors – Putin uses nationalist narratives to bolster domestic popularity and control.

The immediate trigger was Russia’s recognition of the two separatist republics in Eastern Ukraine’s Donbas region – seen by the West as the pretext for invasion.

Timeline and Phases of the Invasion

Russia’s invasion, beginning on February 24, 2022, can be broken into distinct phases showing the evolution of strategies and focus:

Phase 1: Failed Lightning Assault on Kyiv

February 24-April: Russia launched a large-scale invasion across multiple fronts but failed in initial objective of quickly capturing Kyiv and removing Ukraine’s government after facing fierce resistance.

Phase 2: Battle for Donbas

April-July: Russia shifted focus to Donbas region in the east, making slow grinding progress in capturing surrounding areas after weeks of heavy fighting and shelling.

Phase 3: Southern Offensive

August-September: Russia redirected efforts to southern Kherson region, but Ukraine regained some occupied areas here in a counteroffensive.

Phase 4: Bombardment of Infrastructure

October-Present: Facing battlefield setbacks, Russia has unleashed widespread missile and drone attacks on Ukrainian energy and civilian infrastructure.

As the war approaches its one-year mark, many expect a renewed Russian offensive. But the invasion has not followed Moscow’s anticipated quick timeline. Fierce Ukrainian resistance has surprised many and slowed Russia’s advances.

Military Strategies and Tactics

Russia has employed various evolving military strategies and tactics over the different phases of the war:

  • Large-scale air and missile strikes – Russia has fired over 4,700 missiles targeting military and civilian sites.
  • Shelling campaigns – Relentless bombardment of cities like Kharkiv, Mariupol and Kherson has caused extensive damage.
  • Siege warfare – Blockading cities to force surrender, like in Mariupol where fighting destroyed 80-90% of buildings.
  • Assaults on land corridors – Securing land access to Crimea and separatist areas has been a key aim.
  • Battlefield resupply challenges – Poor logistics, maintenance and low troop morale have hindered Russian campaigns.
  • Operational deficiencies and losses – Russia has suffered from poor intelligence, communication failures and high casualty rates.
  • War crimes – Gruesome evidence of summary executions, torture, sexual violence and attacks on civilians.

Ukraine’s tactics have focused on:

  • Adept use of Western-supplied weapons like HIMARS and anti-tank missiles.
  • Strategy of resistance and counteroffensives – Preventing Russian objectives through targeted strikes on supply lines.
  • Urban combat advantage – Leveraging homefield knowledge of terrain.
  • Strategic communication – Rallying global public support and military aid.

Global Response and Role of NATO

The invasion has been met with widespread condemnation and prompted rounds of economic sanctions and military aid:

  • Economic sanctions – Extensive bans on Russian energy, trade, banks and oligarchs imposed by Western nations.
  • Military assistance – Over $50 billion in aid committed by US and NATO allies, providing weapons, training and intelligence support.
  • United UN response – 141 countries condemned Russia’s actions in UN resolution.
  • Refugee crisis – Over 8 million Ukrainian refugees have fled to neighboring countries like Poland.
  • NATO reinforcement – Alliances’ rapid eastern deployment of around 40,000 troops for defense. But no direct intervention so far.
  • Non-aligned stances – China, India and others maintain economic ties with Russia.

Russia’s aggression has unified and reinvigorated NATO, while cracking Putin’s ties with the West. But there are limits to involvement by US and allies wary of escalating the conflict.

Potential Outcomes and Broader Impacts

All sides face pivotal choices ahead that will shape the final outcome and lasting impacts of this war:

  • Russia’s victory – Ukraine forced into concessions, Putin claims win, but Russia faces long-term consequences of sanctions and pariah status.
  • Ukraine’s victory – Pushing Russia back to pre-February lines would be a monumental challenge requiring sustained Western aid.
  • Prolonged conflict – A grinding war of attrition causing extensive damage, civilian suffering and regional instability.
  • Diplomatic resolution – While remote now, a settlement in coming months or years is possible if one side sees advantage in negotiations.
  • Escalation risk – Miscalculation could spark wider conflict between Russia and NATO powers. Use of WMDs by Russia also a concern.

Global economic and political order is shifting significantly from this conflict as it exacerbates divisions between Russia and the West. It also highlights the challenges of applying 20th century institutions like the UN and NATO to modern crises. The war’s human toll already includes tens of thousands dead, millions displaced and its full reverberations may take decades to unfold.
