Proposals for a Ukraine peace deal that accept Russian territorial gains repeat the old pattern of great powers dividing weaker states. It is a pattern set in the partitions of Poland in 1795 and revived in 1939. For Ukraine and its neighbours, these historical memories make any land-for-peace formula look less like conflict resolution and more like the start of another imposed partition.
Echoes of 1795 shape regional distrust, especially when talk of freezing the conflict risks rewarding aggression. Broken commitments such as the Budapest Memorandum deepen Ukraine’s fear that great-power guarantees fail when they’re needed most.
Durable security in Europe depends on recognising that states such as Ukraine cannot be treated as territory to be rearranged by outside powers.
The urgency of this argument lies in the present. As discussion turns again to negotiations, ceasefires and interim settlements, the central question is not whether war should end, but on what terms and with what consequences. In Central and Eastern Europe, proposals that validate Russia’s seizure of land are read through a long historical record in which peace was achieved by dismemberment, legality was manufactured after the fact, and the affected state was excluded from decisions about its own future.
For Ukraine, this is not a theoretical concern. Russia’s annexation of Crimea in 2014 and its attempted annexations of parts of the Donetsk, Luhansk, Zaporizhzhia and Kherson regions after 2022 were presented by Moscow as accomplished facts that diplomacy should accept. Any settlement that leaves those outcomes intact would translate military coercion into recognised borders. In the region’s historical memory, that move has a name. It is partition.
The comparison with 1795 is instructive because it exposes how imposed settlements work. The Third Partition of the Polish–Lithuanian Commonwealth did not follow a consensual peace. It followed the defeat of reformist resistance, diplomatic coordination among the aggressors, and the production of legal instruments to normalise conquest.
The victim state’s consent was irrelevant, even if sought under duress. What mattered was agreement among stronger neighbours and acquiescence by the wider international system. The result was not stability, but the removal of sovereignty for more than a century.
That logic reappeared in 1939. The Molotov-Ribbentrop Pact, with its secret protocol, divided Poland between Nazi Germany and the Soviet Union. Once again, the map was redrawn by outside powers in the name of order and security. The lesson for today is not that history repeats mechanically, but that certain practices recur when aggression is rewarded and borders are treated as negotiable for the sake of convenience.
Ukraine’s fear of betrayal is sharpened by recent diplomatic history. In 1994, Ukraine surrendered the nuclear arsenal it inherited after the collapse of the Soviet Union and acceded to the Treaty on the Non-Proliferation of Nuclear Weapons as a non-nuclear-weapon state. In return, Russia, the United States, and Britain issued the Budapest Memorandum, offering assurances to respect Ukraine’s independence, sovereignty and existing borders. Russia’s invasion makes those assurances central to Ukrainian political memory. They are evidence that formal commitments, even when solemnly recorded, can fail under pressure.
This matters because current peace proposals often rely on the assumption that security guarantees can compensate for territorial loss. From a Ukrainian perspective, that assumption has already been tested and found wanting. If guarantees failed once, why should they be trusted again, especially when the proposed settlement begins by confirming the success of aggression?
The regional response to such proposals is therefore not driven by emotion alone. It reflects a rational assessment shaped by experience. Poland, the Baltic states and Ukraine itself have learned that peace agreements that validate conquest tend to generate further instability. They signal to aggressors that force works and to smaller states that their sovereignty is conditional.
There is also a strategic cost beyond Ukraine. Accepting territorial gains achieved through war would weaken the core principle that has underpinned European security since 1945: the inadmissibility of acquiring territory by force. Once exceptions are made, the norm erodes. The precedent would extend far beyond Ukraine, affecting the calculations of states across Europe’s eastern frontier and beyond.
None of this denies the desire for peace or the human cost of prolonging war. It insists, however, that peace built on coerced loss is not durable. The partitions of Poland showed how quickly imposed settlements could turn into long-term sources of resentment, resistance and renewed conflict. The 20th century confirmed that lesson at catastrophic cost.
If negotiations are to produce security rather than pause violence, they must begin from Ukraine’s sovereignty, not from the map drawn by Russian arms. That does not dictate specific diplomatic mechanisms, timelines or guarantees. It does establish a boundary. Ukraine cannot be treated as a bargaining chip between larger powers without reviving a method of order that Europe has already paid for dearly.
The choice facing today’s policymakers is therefore stark. They can pursue a settlement that echoes 1795 and 1939, translating force into borders and calling it peace. Or they can recognise that a stable Europe depends on breaking with that tradition, and on affirming that Ukraine’s territory, as Poland’s once was, is not available for partition.
