Peak Russian occupation (mid-2022): Russia controlled ~22–25% of Ukraine (including pre-2022 holdings like Crimea and parts of Donbas).
Now Russia occupies ~19–20% of Ukraine.
In 2021 Russia occupied 8% of Ukraine. So in may 2022 they had gained 13% and the lost to today 5%.
So yeah, texasgator is correct that Russia lost a quarter of the Ukrainian land it gained by may 2022.
Kazan, btw isn’t that a city in the Russian federation? Do you live there now as you post this? “Since November of 2022, Russia had gained about 5000 square miles of territory.”
Total since November 2022: Approximately 4,200–5,000 square miles (~11,000–13,000 sq km), with most occurring in 2024–2025 amid intensified Russian offensives around Pokrovsk and other Donbas areas.
Impressive clawing back over 3 years and at the loss of lives and money
That doesn't, in anyway, negate the point I made -- since November of 2022, Russia has been gaining territory. It's more than three years since Ukraine "took" any territory back.
For more than two years, the primary Russian goal has been destroy the Ukrainian military, not take territory.
The only territory left that Russia wanted going into the war is what is left of Donetsk that isn't under Russian control.
