Nearly four and a half years after Russia launched its full-scale invasion of Ukraine on February 24, 2022, Europe remains trapped in its most destructive war in generations. Cities have been shattered, families displaced, soldiers killed by the hundreds of thousands according to varying estimates, and civilians continue to die far from the battlefield. Yet despite repeated diplomatic initiatives, neither a durable ceasefire nor a credible political settlement is in sight.

The starting point must remain clear. Russia launched the full-scale invasion of a sovereign neighboring country. In March 2022, the United Nations General Assembly overwhelmingly adopted a resolution demanding that Russia end its invasion and withdraw its forces from Ukraine. Whatever legitimate debates may exist over NATO enlargement, European security arrangements or Western policy toward Moscow, none provides a legal license for one country to seize another country’s territory by military force.

The human cost is getting worse, not better

The most disturbing reality is that the suffering is increasing even as the war becomes almost routine in international headlines.

United Nations monitors recorded 437 civilians killed and 2,610 injured in Ukraine during July 2026 alone, making it the highest monthly civilian casualty level documented since the early months of the invasion. During the first seven months of 2026, the UN verified 1,839 civilian deaths and 10,638 injuries — a 44% increase over the same period of 2025. The actual numbers are likely higher because many deaths, particularly in occupied territory, cannot immediately be verified.

Ukraine has increasingly used long-range drones against Russian military, industrial and energy targets, while Russia has continued large-scale missile, drone and glide-bomb attacks across Ukraine. The expansion of strikes deep behind the front lines demonstrates how this war is evolving from a territorial ground conflict into an increasingly dangerous long-range confrontation.

And the danger is not confined to conventional weapons. On August 8, the Russian-controlled Zaporizhzhia Nuclear Power Plant temporarily lost all external power for the 25th time since the conflict began. The International Atomic Energy Agency says repeated military activity around the plant continues to create a fragile nuclear-safety situation. A serious accident there would not recognize Russian, Ukrainian or NATO borders.

There will be no simple military victory

Both Moscow and Kyiv continue to believe battlefield pressure can improve their negotiating positions. Russia still occupies substantial Ukrainian territory and has demanded that Ukraine surrender control of regions Moscow claims as Russian. Ukraine rejects those demands and insists that any settlement provide genuine security guarantees against another invasion. Recent fighting remains intense, with both sides claiming territorial and strategic gains.

The problem is that every additional kilometer of territory is being purchased with lives, destroyed communities and billions of dollars.

The World Bank’s February 2026 assessment estimated Ukraine’s recovery and reconstruction requirements at almost $588 billion over the coming decade, with direct physical damage already exceeding $195 billion by the end of 2025. Those figures continue to rise with every destroyed apartment building, bridge, power station, factory and school.

This war therefore cannot be measured only by maps showing which army gained a village this week. Its true cost is being written into an entire generation.

Russia’s concerns can be discussed — sovereignty cannot simply be erased

Moscow argues that NATO expansion, Ukraine’s Western military relationships and Russia’s broader security concerns are among the conflict’s “root causes.” Those issues can and should be discussed in negotiations. A durable European security system ultimately has to consider the legitimate security interests of Russia, Ukraine and neighboring states.

But there is an important distinction between negotiating security arrangements and accepting territorial conquest as normal international behavior.

If borders can simply be changed by invasion and occupation, the consequences extend far beyond Ukraine. Smaller nations everywhere would have reason to question whether international law protects them when confronted by a more powerful neighbor.

At the same time, peace cannot be achieved by pretending Russia will disappear from Europe’s security landscape. Russia is a nuclear-armed power and will remain Ukraine’s neighbor. Any lasting settlement will therefore require diplomacy with Moscow, however difficult that diplomacy may be.

Ukraine’s supporters also have responsibilities

Western countries were justified in helping Ukraine defend itself against invasion. But military assistance must remain connected to a political objective: a secure and sustainable peace, rather than an indefinite war without a realistic end state.

Ukraine, for its part, must continue strengthening democratic institutions, transparency and accountability even under the extraordinary pressures of wartime. Defending democracy cannot ultimately mean suspending democratic standards indefinitely.

Meanwhile, Ukraine and Russia must both comply with international humanitarian law. Civilian populations, hospitals, energy systems necessary for civilian survival and commercial shipping cannot become acceptable instruments of pressure simply because the enemy uses similar tactics.

Recent disputes in the Black Sea illustrate the broader danger. Ukraine proposed halting attacks on civilian shipping, while Russia rejected the idea of a limited Black Sea ceasefire. With both countries major agricultural exporters, disruption of ports and shipping threatens food markets far beyond Europe.

What should happen now?

The international community should push urgently for a phased diplomatic process.

The first objective should be a verifiable ceasefire, accompanied by international monitoring. Attacks on civilian energy infrastructure and commercial shipping should stop. Prisoner exchanges and the return of civilians should accelerate. Special arrangements around nuclear facilities must be insulated from military operations.

Territorial questions may prove far more difficult and could require years of negotiation. A ceasefire does not necessarily have to constitute legal recognition of territorial changes. History offers many examples where fighting stopped while sovereignty disputes remained unresolved.

Most importantly, Ukraine will need credible security guarantees. A document that merely promises future consultations would not be enough after the experience of this war. Russia, meanwhile, would need clarity about the future military architecture on its borders and a defined pathway under which sanctions could be eased if a settlement is honored.

Peace will inevitably require compromise. But compromise is not the same as surrender, and diplomacy is not the same as rewarding aggression.

After more than four years of death and destruction, continuing the war simply because ending it is politically difficult would be a failure of leadership.

Russia cannot erase Ukraine’s sovereignty. Ukraine cannot change the geographic reality that Russia will remain beside it. Europe cannot remain permanently organized around an expanding battlefield between nuclear powers.

The objective now should not be victory for one political narrative over another. It should be a settlement in which Ukraine can survive as an independent and secure nation, Russia receives legitimate security through negotiation rather than conquest, and ordinary people on both sides are finally allowed to stop burying their dead.

That is not an easy peace.

But after everything this war has already destroyed, it is the peace the world must work much harder to achieve.
