History does not repeat itself, but it often rhymes—and right now the rhyme is slipping into a discordant howl. The latest diplomatic row between Poland and Ukraine, ostensibly over a controversial WWII-era Ukrainian nationalist unit, has exposed a fissure in what was once a near-unshakeable bulwark against Russian aggression. Warsaw’s decision to summon Ukraine’s ambassador, coupled with President Duda’s frosty public snub of Volodymyr Zelensky, is not merely a petty squabble. It is a symptom of a deeper malady: the fraying of the Western consensus that has sustained Ukraine’s defence.
The issue at hand is the Ukrainian Insurgent Army (UPA), a nationalist formation that fought both Soviet and Nazi forces but is also accused of massacring tens of thousands of Poles during the Second World War. For Poles, this is not ancient history; it is a wound that remains raw. For Ukrainians, the UPA represents a struggle for independence—a nuance that has become increasingly difficult to maintain under the pressures of war. The UK, ever the diplomatic hand-wringer, has called for restraint. But restraint is a luxury for those who do not have to face the emotional weight of history.
What we are witnessing is the return of the repressed. The Western alliance, held together by the common threat of Russia, is now facing internal stresses that were always there—ethnic grievances, historical grudges, competing narratives. The Poles, who have been among Ukraine’s most vocal supporters, are now signalling that their patience has limits. And if Poland, a frontline state with a deep visceral understanding of Russian imperialism, begins to waver, what does that say about the broader commitment?
Zelensky’s government, for its part, has tried to downplay the row, but the symbolism is damning. The Ukrainian president, once a darling of Western capitals, is now being treated as a supplicant—one whose requests are met with a raised eyebrow rather than open arms. This is a far cry from the heady days of 2022, when solidarity was the order of the day. Now, the talk is of fatigue, of rising costs, of domestic priorities. And the Poles, with their own elections and internal anxieties, are simply the first to say what others are thinking: that Ukraine cannot be allowed to rewrite history to suit its present needs.
All this plays directly into the hands of Vladimir Putin, who must be watching with grim satisfaction. The Kremlin’s strategy has always been to outlast Ukrainian resolve and Western support. To see Poland and Ukraine at loggerheads over a historical grievance is to see that strategy bearing fruit. The Russian narrative—that Ukraine is a hotbed of fascist nationalism—gains a veneer of plausibility when Poland itself calls out Ukrainian historical revisionism. Never mind that the current Ukrainian government is a multi-ethnic, liberal democracy under siege; the optics are what matter.
The UK’s call for restraint is, of course, the right diplomatic stance. But diplomacy has its limits when the two parties are locked in a zero-sum struggle over the past. What is needed is a more sober reckoning: the West must accept that the grand coalition against Russian aggression is not a permanent fixture. It is a contingent arrangement, held together by fear and self-interest. And as those forces begin to recede, the old quarrels will re-emerge.
I am not suggesting that the West is on the brink of collapse. But the Polish-Ukrainian spat is a warning. It is a reminder that history is not a closed book; it is a live wire, capable of shocking us at any moment. If we are to maintain the unity that has been so painstakingly built, we must do more than paper over the cracks. We must engage with the past honestly, even if it means confronting uncomfortable truths about our own allies. Otherwise, the cracks will widen, and the entire edifice will come tumbling down.
