What’s Happening

As of early September 2026, the prospect of NATO/EU troops fighting in Ukraine remains a distant scenario, with the alliance continuing a deliberate policy of escalation management through training and strike support rather than direct engagement. Ukrainian forces are conducting an intermediate-range strike campaign against Russian military assets in occupied Crimea, targeting drone storage and communications hubs near Hvardiiske and Myrne on August 31, according to the Ukrainian General Staff. This operational tempo underscores Kyiv’s capacity to strike deep behind enemy lines without requiring NATO/EU troops fighting in Ukraine, a red line that Western leaders have maintained since the invasion began in February 2022. The strikes come as the United States plans to deploy the Typhon missile system in Europe in 2026, with Germany also purchasing the capability, signaling a new theater-range missile arms race between Russia and NATO that stops short of direct combat involvement.

The training pipeline on NATO soil has expanded significantly, with Operation Legio, led by Norway and several allies at Camp Jomsborg in eastern Poland, operating roughly two hours from the Ukrainian border. This program, alongside the UK-led Operation Interflex, is designed to rotate Ukrainian troops through advanced combat training while keeping allied personnel physically outside Ukraine’s sovereign territory. The proximity of Camp Jomsborg to the frontline highlights a calculated risk: NATO is preparing Ukrainian forces for high-intensity warfare but has not authorized allied soldiers to cross the border. Polish defense expert Withold Rodkiewicz noted that the Kremlin is frustrated by its inability to break Ukrainian armed forces in the field, and Moscow may conclude that the only path to victory is to politically break NATO—a dynamic that raises the stakes for any accidental escalation but has not yet shifted the calculus on deploying NATO/EU troops fighting in Ukraine.

The structural factor determining whether NATO/EU troops fighting in Ukraine becomes a reality by December 31, 2026, lies in Russia’s strategic response to Ukraine’s deep-strike campaign and NATO’s missile deployments. A Carnegie Endowment analysis from March 2026 warns that the return of theater-range missiles in Europe, driven by the Typhon system and Germany’s planned purchases, is creating a new geography of standoff that mirrors the Cold War INF Treaty contest but with more participants. Meanwhile, CBC News reports that the war is approaching a critical turning point, with Moscow potentially viewing a political break of NATO as its only viable strategy. Analysts caution that while direct NATO intervention remains unlikely, the combination of Russian desperation, missile proliferation, and training missions near the border creates a volatile environment where miscalculation could trigger a response. For now, the 7% probability reflects a consensus that allied governments will continue to support Ukraine through arms, training, and intelligence—but will stop short of committing ground forces to combat operations before the year’s end.
