Timeline of Major Events

From the February 2022 invasion through the diplomatic efforts of early 2026. Major events marked with larger dots.

2022
24 February 2022
Russia launches full-scale invasion
At approximately 3:40 a.m. Kyiv time, Russia began the largest military operation in Europe since World War II, advancing along four axes toward Kyiv, Kharkiv, the Donbas, and southern Ukraine from Crimea.
24 Feb – 2 Apr 2022
Battle of Kyiv
Russian forces advanced rapidly from Belarus toward the capital. Ukrainian forces and armed civilians mounted fierce resistance, bogging down a 64-km-long Russian convoy. Russia withdrew from the Kyiv region by early April, abandoning its plan for a rapid decapitation strike.
24 Feb – 20 May 2022
Siege of Mariupol
Nearly three months of bombardment destroyed the strategic port city. The last defenders at Azovstal surrendered on 20 May. Civilian death toll estimated in the tens of thousands.
1–3 April 2022
Bucha massacre revealed
As Russian forces withdrew from Kyiv suburbs, evidence emerged of mass killings of civilians in Bucha — 458 bodies recovered, many with hands bound. The revelations prompted international condemnation and war crimes investigations.
14 April 2022
Sinking of the Moskva
The flagship of Russia's Black Sea Fleet was struck by two Ukrainian Neptune anti-ship missiles and sank — the largest warship lost in combat since the Falklands War.
6–16 September 2022
Kharkiv counteroffensive
Ukraine launched a surprise counteroffensive, liberating over 12,000 sq km including Izium and Kupiansk in just weeks. A deception campaign had drawn Russian reserves to the south.
21 September 2022
Russian "partial mobilisation"
Putin announced mobilisation of 300,000 reservists, triggering an exodus of 500,000–700,000 military-age men from Russia and large anti-war protests.
11 November 2022
Liberation of Kherson
Ukrainian forces entered Kherson city after Russia withdrew from the western bank of the Dnipro — the only regional capital Russia had captured.
2023
Aug 2022 – May 2023
Battle of Bakhmut
The longest battle of the war. Russia's Wagner Group spearheaded the assault using recruited prisoners as assault troops. Nearly 20,000 Wagner fighters died, with total Russian casualties estimated at 60,000–100,000.
6 June 2023
Kakhovka Dam destroyed
The dam on the Dnipro was destroyed under Russian control, causing massive flooding, ecological devastation, and displacing thousands downstream in Kherson Oblast.
June – October 2023
Ukraine's summer counteroffensive stalls
Ukraine's long-anticipated offensive in Zaporizhzhia and Donetsk faced deep Russian defences, dense minefields, and drones. Progress was minimal. The operation failed to breach the Russian "land bridge" to Crimea.
23–24 June 2023
Wagner Group mutiny
Prigozhin launched a "march of justice," seizing Rostov-on-Don and advancing within 200 km of Moscow before halting under a Belarus-brokered deal. The most serious internal challenge to Putin's rule in two decades.
23 August 2023
Prigozhin killed
Exactly two months after the mutiny, Prigozhin's plane crashed near Moscow. U.S. intelligence assessed intentional sabotage. Widely interpreted as Kremlin retribution.
2024
16 February 2024
Navalny dies in prison
Russia's most prominent opposition leader died in an Arctic penal colony. In February 2026, five Western nations said he was killed by epibatidine, a poison-frog toxin. Russia disputes this.
17 February 2024
Fall of Avdiivka
After four months of fighting, Ukraine withdrew from the heavily fortified Donetsk city. Russia suffered an estimated 47,000 casualties in the assault.
April 2024
US approves $61B aid after months of delay
Republican opposition delayed the package for months, causing ammunition shortages along the front and contributing to the fall of Avdiivka.
6 August 2024
Ukraine's Kursk incursion
Ukraine launched a surprise cross-border offensive into Russia's Kursk Oblast, capturing approximately 1,300 sq km. Strategic purpose debated — Russia later recaptured most territory with North Korean support.
October 2024
North Korean troops deployed
Multiple intelligence agencies confirmed ~12,000 North Korean troops sent to Russia, deployed in Kursk. By February 2026, an estimated 6,000 had been killed or wounded.
2025
20 January 2025
Trump takes office
The new administration immediately signalled a shift toward prioritising a negotiated settlement, having promised to end the war "in 24 hours."
28 February 2025
White House confrontation
A meeting between Trump, Vance, and Zelenskyy turned confrontational. The minerals deal was not signed. Zelenskyy was asked to leave. Widely seen as a low point in US-Ukraine relations.
March 2025
US aid briefly paused
Trump ordered a pause on military aid including air defence and intelligence sharing. The freeze lasted about a week. The administration did not seek new congressional funding for Ukraine.
Summer–Autumn 2025
Russian grinding advances continue
Russia captured Chasiv Yar and Pokrovsk in Donetsk Oblast, advancing roughly 70 metres per day on average. Russia gained 5,000 sq km over the year — an additional 0.8% of Ukraine's territory — at the cost of ~400,000 casualties.
20 November 2025
Trump's 28-point peace plan
The administration presented a detailed proposal: Ukraine would cede Donbas territory, accept a military cap and NATO exclusion. In exchange: a security guarantee and $100B in frozen Russian assets for reconstruction. Criticised by both sides of Congress and European allies.
December 2025
Trump-Zelenskyy Florida talks — "90% agreed"
A trimmed 20-point version was discussed. Both sides claimed 90% agreement, but the remaining 10% encompassed the most intractable issues: Donetsk status, demarcation, and security guarantees.
2026
6 January 2026
Paris summit: "Coalition of the Willing"
35 countries gathered. France and the UK pledged to deploy up to 15,000 troops to Ukraine as part of a ceasefire monitoring mechanism. The US backed security guarantees.
January–February 2026
Abu Dhabi and Geneva trilateral talks
Three rounds of US-brokered talks between Ukraine, Russia, and the US — the first sustained direct negotiations since 2022. A prisoner exchange was agreed, but no breakthrough on territory or security guarantees.
29 January 2026
Ukraine counterattacks in Dnipropetrovsk
Ukraine liberated over 400 sq km in Dnipropetrovsk Oblast — the first significant territorial gain since the Kursk incursion. February 2026 was the first month since 2024 where Ukraine regained more territory than it lost.
March 2026
Peace talks paused
The next round of trilateral talks was postponed as the Trump administration's attention shifted to the Iran conflict. Both sides claim readiness to continue. Fighting continues across the 1,000 km front.

Military Situation

Front lines, force composition, Western weapons, drones, and the human cost.

Russia traded over 400,000 casualties for 0.8% of Ukrainian territory in 2025.
CSIS analysis, January 2026

Front Lines (March 2026)

Russia occupies approximately 20% of Ukraine's internationally recognised territory (~116,000 km²), including Crimea, most of Luhansk and Donetsk oblasts, and parts of Zaporizhzhia and Kherson oblasts south of the Dnipro.

Russian gains have slowed markedly in early 2026. February saw Russia's smallest monthly territorial gain since July 2024. Meanwhile, Ukraine launched counterattacks in Dnipropetrovsk Oblast liberating over 400 km² — the first month since 2024 where Ukraine regained more territory than it lost.

ISW assesses Russia is preparing a spring-summer 2026 offensive targeting Slovyansk-Kramatorsk and/or Zaporizhzhia, but Ukraine's counterattacks may be burning through Russian operational reserves.

Force Composition

Russia

Russia recruited approximately 422,000 personnel in 2025 and targets 409,000 for 2026. The Kremlin avoids formal mobilisation, relying on contract soldiers, foreign recruits, and — increasingly — coercive methods. Tank production is scaling to 428 T-90M/M2 tanks per year by 2028. However, Russia has shifted to "demechanised" warfare: gaining 30% more ground in 2025 while using fewer tanks, instead relying on dismounted infantry, FPV drones, and glide bombs.

Ukraine

Ukraine faces a severe manpower crisis. It needed 300,000 recruits in early 2025 but managed only ~200,000. AWOL cases surged to 576 per day by mid-2025. The mobilisation age was lowered to 25 in 2024, but coercive recruitment undermines motivation.

Western Weapons

The US has provided $66.9 billion in military assistance since 2022, but new support declined 99% under Trump. Europe has stepped up: military aid rose 67%, and the EU approved €90 billion in loans for 2026-2027.

Note on weapon performance: Western tanks (Abrams, Leopard 2) have underperformed expectations due to FPV drone vulnerability. HIMARS, Patriot air defence, NASAMS, and F-16s remain the most impactful systems.

The Drone War

Drone warfare defines this conflict. Ukraine aims to produce 7 million military drones in 2026. Interceptor drones now down 70%+ of Russian Shaheds near Kyiv at a 1:50 to 1:150 cost ratio versus traditional air defence. Russia has responded with jet-powered glide bombs extending range to 150-200 km, dropping a record 5,717 aerial bombs in January 2026 alone.

North Korean Troops

Approximately 15,000 North Korean troops deployed to Russia since late 2024. South Korean intelligence estimates ~6,000 casualties (killed + wounded) by February 2026. Deployed primarily in Kursk.

Casualties caveat: All casualty figures are deeply uncertain. CSIS estimates 275,000–325,000 Russian and 100,000–140,000 Ukrainian military fatalities through December 2025. Combined casualties may approach 2 million by spring 2026. These are rough estimates with wide error margins.

Diplomacy & Peace Efforts

From Minsk to Istanbul to Trump's 28-point plan — four years of failed negotiations and shifting alliances.

Minsk Background (2014-2022)

The Minsk agreements of 2014 and 2015 aimed to resolve the Donbas conflict through ceasefire, decentralisation, and elections. They were never implemented. Both sides accused the other of violations, and sequencing disputes (elections first or border control first) proved intractable. Former Chancellor Merkel later acknowledged Minsk also served to buy Ukraine time to strengthen its military.

Istanbul Talks (March 2022)

The most substantive negotiations produced a framework: Ukrainian neutrality in exchange for security guarantees, limits on military size, EU membership permitted, and deferred discussion of Crimea and Donbas. The talks collapsed after the Bucha massacre hardened Ukrainian opinion, and the improving military situation reduced Kyiv's incentive to concede.

Peace Plans (2022-2024)

Zelenskyy's 10-point formula (November 2022) was maximalist: full withdrawal to pre-2014 borders including Crimea, war crimes tribunal, reparations. Russia rejected it outright.

China's 12-point position paper (February 2023) called for ceasing hostilities and ending sanctions but did not condemn the invasion or call for Russian withdrawal. Western analysts characterised it as aligned with Russian interests.

The Burgenstock summit (June 2024) in Switzerland drew 100 delegations but Russia didn't attend and key Global South nations declined to sign the communique.

Trump Administration Approach (2025-2026)

Trump promised to end the war "in 24 hours" but results have been mixed. Special envoy Kellogg was sidelined. The White House confrontation with Zelenskyy (February 2025) was a public low point. Intelligence sharing was briefly paused. The minerals deal was eventually signed in April 2025.

The 28-point peace plan (November 2025) proposed: ceding Donbas de facto, capping Ukraine's military, barring NATO membership, with $100B in frozen assets for reconstruction and US receiving 50% of profits. Critics called it heavily pro-Russian. A December meeting produced the "90% agreed" claim, but core issues remained unresolved.

Trilateral Talks (January-February 2026)

Three rounds of US-brokered talks in Abu Dhabi and Geneva — the first sustained negotiations since 2022. A prisoner exchange was agreed. Envoy Witkoff claimed talks were "down to one issue" (territory). But the Geneva round ended abruptly after two hours, and Russia launched strikes during the talks.

As of 18 March 2026, talks are paused due to the Iran conflict. Zelenskyy says Ukraine is ready to continue. Russia shows no urgency.

European Response

The war catalysed the largest European defence build-up since the Cold War. NATO raised its spending target to 5% of GDP by 2035. Poland leads at 4.48%. Germany amended its constitution to exempt defence spending from the debt brake, projecting €83B for 2026. The EU's ReArm Europe plan enables up to €800 billion in additional defence spending through 2030.

Sanctions & Economic Impact

The sanctions regime, Russia's resilience, energy disruption, and Ukraine's reconstruction challenge.

Sanctions

19 EU Packages

The EU has adopted 19 sanctions packages, covering trade, energy, finance, and 2,200+ designated individuals. The US imposed new sanctions on Rosneft and Lukoil in October 2025 under Trump.

Energy

Russian Gas: 40% → 6%

Russia's share of EU pipeline gas fell from 40% to 6%. The EU adopted a full ban on all Russian gas (pipeline + LNG) to be phased out by end 2027.

Frozen Assets

$300 Billion

Russian Central Bank reserves frozen globally, now indefinitely. Interest income funds EU loans to Ukraine. Full confiscation remains debated but kept as a future option.

Russian Economic Resilience

Russia's GDP growth slowed from 4.1% (2024) to ~1% (2025), with stagnation forecast for 2026. The economy overheated from military spending; the central bank raised rates to 21% before cutting to 15.5%. A shadow fleet of ~978 tankers carries 68% of Russian crude exports, circumventing the oil price cap. China and India receive 80% of Russian oil.

The economy has split: a growing military-industrial sector and a stagnating civilian economy. 31% of Russians now struggle to afford food, and the country faces a projected labour shortage of 10.9 million workers by 2030.

Military-Industrial Complex

Defence spending reached $175 billion in 2025 (~7.2% of GDP), consuming nearly 40% of federal spending. Artillery shell production expanded 17-fold. Russia produces three times more shells than the US and Europe combined for Ukraine. However, there are signs the defence-sector boom may have peaked.

Ukraine's Economy

GDP remains 21% below pre-war levels. Reconstruction costs are estimated at $588 billion over 10 years. Western aid exceeds $400 billion total. The EU approved €90 billion in new loans for 2026-2027. Ukraine's 2025 budget depended on $38.4 billion in Western aid to cover a deficit of 19.6% of GDP.

Grain Exports

After Russia exited the Black Sea Grain Initiative in July 2023, Ukraine established its own corridor through NATO-aligned waters, exploiting its neutralisation of the Russian Black Sea Fleet. Ukraine remains a top-5 global grain exporter, though volumes remain below pre-war benchmarks.

Internal Politics

Domestic dynamics in Russia and Ukraine — repression, mobilisation, and the human cost of war.

Russia

Repression

14,900+ detained at anti-war protests. 1,000+ criminal cases. 820–2,000+ political prisoners. 700,000 websites blocked. 15-year sentences for calling the war "a war."

Russia

Brain Drain

~1.3 million emigrated in 2022, 70% with higher education. 100,000+ IT specialists left. Only 8% returned between 2023–2024. Labour shortage of 10.9M projected by 2030.

Ukraine

Mobilisation Crisis

AWOL rates surged to 576/day by mid-2025. ~2 million estimated evading the draft. Draft age lowered to 25, but coercive recruitment undermines morale and effectiveness.

Russian Domestic Situation

War support has eroded significantly. The Levada Center found only 25% of Russians support continuing the war as of December 2025 — the lowest since the invasion. 66% favour peace talks. Putin won re-election in March 2024 with 87% in what Meduza called "almost certainly the most fraudulent" Russian election in modern history.

Wagner Mutiny and Aftermath

Prigozhin's 36-hour rebellion in June 2023 was the most serious challenge to Putin's authority in two decades. His assassination two months later was widely seen as the Kremlin's reassertion of its monopoly on violence. Wagner was rebranded as the state-controlled Africa Corps in December 2023.

Navalny's Death

Alexei Navalny died in an Arctic penal colony on 16 February 2024. Russia claimed natural causes. In February 2026, the UK, France, Germany, Sweden, and the Netherlands identified the cause as epibatidine, a laboratory-made toxin. His widow Yulia Navalnaya has emerged as the leading opposition figure in exile.

Ukrainian Politics

Martial law has been extended 18 times through May 2026, preventing elections. Zelenskyy's term nominally expired in May 2024, but constitutional lawyers consider his continuation lawful. Under Trump pressure, Zelenskyy indicated readiness for elections within 60-90 days if security guarantees are provided.

War Fatigue on Both Sides

Ukrainian support for "fighting until victory" dropped from 73% (2022) to 24% (2025). However, 76% reject peace on Russian terms. On the Russian side, 55% expect the war to end in 2026, but only a third would support returning annexed territories.

Polling caveat: Polling in authoritarian Russia must be interpreted cautiously — respondents may conceal true views. Even the relatively independent Levada Center's results are debated by experts.

Analysis & Outlook

Where the war stands, where it might go, and what the world is learning.

The conditions for a durable settlement do not yet exist.
Brookings multi-author analysis, February 2026

State of Play

Neither side holds decisive momentum. Russia has more mass but is suffering unsustainable casualties. Ukraine has more innovation and Western support but faces critical manpower constraints. The situation is strategic stalemate — both sides capable of localised operations, neither able to break through.

Likely Trajectories

Most likely: Continued attritional stalemate

The war continues at roughly current intensity with slow Russian gains offset by periodic Ukrainian counterattacks. Steven Pifer (Stanford/Brookings) assesses "the war will continue" as the most probable outcome. Conditions for settlement do not yet exist.

Possible: Negotiated settlement by late 2026

The Trump administration's June 2026 deadline, trilateral talks, and French/UK troop pledges suggest diplomatic machinery is being assembled. But Brookings characterises Trump's mediation as "a year of failure," and core issues remain far apart.

Lower probability: Frozen conflict

The war de-escalates without formal settlement. A de facto ceasefire emerges along current lines — analogous to Korea. International attention shifting to other crises makes this more plausible.

What a Settlement Might Look Like

  • Territory: De facto frozen line of control without formal cession — analogous to the inter-Korean border
  • Security: European troop deployments (France/UK), US monitoring via drones/sensors, Ukrainian self-defence capacity
  • NATO: Off the table for the foreseeable future; Russia considers blocking membership a core war objective
  • Economics: Conditional sanctions relief tied to compliance; frozen asset interest for reconstruction; EU membership fast-tracking

Key Uncertainties

  • US policy: The single largest variable. Trump has sent mixed signals — minerals deal vs. oil sanctions rollback
  • European commitment: $197B provided so far, but sustaining this over years will strain budgets and political will
  • Russian staying power: Economy slowing but not collapsing; recruitment sustaining losses but pool not infinite
  • Ukrainian manpower: The most critical operational challenge; 140,000 killed, plus millions fled abroad
  • Iran conflict: Competing for Western attention, resources, and potentially redirecting defensive munitions

Lessons Learned

Military

  • Drone revolution: FPV drones are the dominant weapon; naval drones achieved sea denial without a navy; drone-vs-drone warfare creates rapid innovation cycles
  • Return of attrition warfare: Manoeuvre warfare has proven extremely difficult against prepared defences with extensive surveillance
  • Fortifications matter: The Surovikin Line blunted Ukraine's 2023 offensive; Ukrainian fortifications have slowed Russian advances
  • Industrial base matters more than initial stockpiles: Both sides had to crash-produce ammunition and equipment; Western procurement systems proved too slow
  • Electronic warfare is decisive: Both sides invest heavily in EW to jam drones, communications, and GPS

Political & Strategic

  • Sanctions are a slow weapon: Imposed costs and constraints but did not cause collapse or compel behavioural change
  • Alliance cohesion depends on domestic politics: The Western response was more unified than expected, but Trump's shifts show it cannot be taken for granted
  • Nuclear deterrence constrains response: Russia's arsenal limited Western intervention, creating a paradox where nuclear weapons enable conventional aggression
  • Energy interdependence is a vulnerability: Europe's pre-war dependence on Russian gas proved a critical weakness
  • Conventional deterrence failed: Russia invaded despite NATO and sanctions because Putin calculated the costs were manageable
