Four years into Russia's full-scale invasion, Ukrainian President Volodymyr Zelenskyy declared that Vladimir Putin has not achieved his war aims. Speaking on the war's anniversary, Zelenskyy stated Ukraine has successfully defended its independence and statehood.

He described the initial days of the invasion as the "longest day of our lives," acknowledging the fear and shock felt by Ukrainians. However, he emphasized a collective understanding that "this is our home, and all of us understood what had to be done." Zelenskyy lauded the courage of Ukrainians for defending their nation rather than surrendering.

The conflict, now in its fifth year, has become Europe's deadliest since World War II. Many European nations have increased defense spending amid ongoing threats from Moscow. Peace talks, relaunched by the United States, have failed to cease hostilities.

International leaders, including European Commission chief Ursula von der Leyen, are visiting Ukraine to mark the anniversary, reaffirming unwavering support. Von der Leyen stated Europe stands with Ukraine "financially, militarily, and through this harsh winter," vowing not to relent until "peace is restored. Peace on Ukraine's terms."

Estimates suggest over 1.8 million soldiers have been killed, wounded, or missing on both sides. The Centre for Strategic and International Studies (CSIS) places Russian casualties around 1.2 million, with up to 325,000 troop deaths. Ukraine faces 500,000 to 600,000 military casualties, including up to 140,000 deaths.

Independent verification of military losses is difficult. The BBC and Mediazona have verified at least 177,000 Russian soldier deaths through public records.

Millions of Ukrainians have been displaced, with 5.9 million refugees living abroad and 3.7 million internally displaced. The UN has verified over 15,000 civilian deaths, but the actual number is likely higher.

Widespread destruction has reduced Ukrainian cities to rubble. Over 2,800 attacks on healthcare facilities have been verified, and Russian assaults on energy infrastructure have caused power outages for millions. Approximately 20% of Ukraine is contaminated by mines or unexploded ordnance.

The estimated cost of reconstruction over the next decade is $588 billion. Peace talks remain at an impasse, with Russia seeking control of eastern regions and a halt to Western military support, demands Ukraine deems unacceptable and a threat to its security.
