Russia controls 20% of Ukraine after 4 years of war — here's what's happening on the ground, what Ukraine has lost, and the three ways this war could end.
On 24 February 2022, Russia invaded Ukraine in the largest European war since 1945. Four years later, the war has killed over 500,000 soldiers (both sides combined), displaced 8 million Ukrainians, and cost the global economy $1 trillion in lost growth, energy shocks, and food shortages. Russia controls 20% of Ukraine (109,000 km²) including Crimea, Donetsk, Luhansk, and parts of Zaporizhzhia and Kherson oblasts. The war has settled into WWI-style trench warfare with 1,000+ casualties per day on both sides, and no end in sight.
Ukraine's 2023 counteroffensive — backed by $100 billion in Western weapons (tanks, artillery, air defence) — failed to break Russian lines, advancing just 10km in six months at the cost of 30,000 Ukrainian casualties. Since then, Russia has slowly advanced in Donbas (1-2km per month), grinding forward through minefields, trenches, and fortified villages. Ukraine is holding the line but losing ground.
Western military aid totals $380 billion (2022-2026), but Ukraine faces ammunition shortages while Russia outproduces the West 3:1 in artillery shells. The war will likely end in a frozen conflict (Korea-style armistice), a negotiated settlement (Ukraine cedes territory for peace), or Ukrainian collapse (if Western aid stops). Full Ukrainian victory (recapturing all territory including Crimea) is unlikely. Here's where the war stands, what Ukraine has lost, and how it could end.
Russia controls 20% of Ukraine (109,000 km² out of 603,000 km²):
Annexed by Russia in 2014 (before the 2022 invasion). Russia has controlled Crimea for 12 years and has integrated it into Russia (Russian passports, Russian currency, Russian military bases). Ukraine has no realistic prospect of recapturing Crimea militarily.
Russia controls 80% of Donetsk and 100% of Luhansk (the two oblasts that make up the Donbas region). Russia has been fighting in Donbas since 2014 (before the 2022 invasion) and declared Donetsk and Luhansk "independent republics" in February 2022. Russia formally annexed Donetsk and Luhansk in September 2022 (along with Zaporizhzhia and Kherson).
Current fighting: Russia is slowly advancing in Donetsk (1-2km per month), capturing fortified villages (Avdiivka fell in February 2024, Bakhmut fell in May 2023). Ukraine is defending but losing ground.
Russia controls 70% of Zaporizhzhia (including Zaporizhzhia nuclear power plant, Europe's largest) and 30% of Kherson (the east bank of the Dnipro River).
Ukraine recaptured Kherson city in November 2022 (Russia's only major territorial loss since the invasion), but Russia still controls the east bank of the Dnipro River.
Current fighting: The front line is static along the Dnipro River. Neither side can cross the river (too wide, too well-defended).
Russia controls 109,000 km² (20% of Ukraine), including:
This is an area the size of England (130,000 km²) or Pennsylvania (119,000 km²).
The war has settled into WWI-style trench warfare:
Russia is pursuing a war of attrition:
Ukraine is pursuing a defensive strategy:
Ukraine's 2023 counteroffensive failed because:
The 2024 situation is worse: Ukraine has fewer soldiers (700,000 vs 1.3 million Russian), less ammunition (Western production has increased but still lags Russia), and no clear path to breaking Russian lines.
The war is the deadliest European conflict since WWII:
Russia is losing 1,000+ soldiers per day (killed + wounded), the highest casualty rate since WWII.
Ukraine is losing 500-800 soldiers per day (killed + wounded).
Both sides have lost more equipment than most countries possess.
Western countries have provided $380 billion in military aid to Ukraine (2022-2026):
Western aid is not enough:
A Korea-style armistice: fighting stops, but no peace treaty. Russia keeps occupied territory (20% of Ukraine), Ukraine keeps the rest. A demilitarised zone is established along the front line. Both sides claim victory and refuse to negotiate.
Precedent: Korean War (1950-1953) ended in armistice, not peace treaty. North and South Korea are still technically at war 70 years later.
Pros: Stops the killing, allows reconstruction, gives Ukraine time to rebuild military Cons: Russia keeps occupied territory, Ukraine does not regain sovereignty, war could restart at any time
Likelihood: 60%
Ukraine and Russia negotiate a peace deal:
Precedent: Finland ceded 10% of territory to USSR in 1940 (Winter War) in exchange for peace
Pros: Ends the war, Ukraine gets NATO membership, reconstruction begins Cons: Ukraine loses 20% of territory, Russia "wins", sets precedent for territorial conquest
Likelihood: 30% (only if Western aid stops or Ukraine faces collapse)
