After more than four years of war, a question once unthinkable to say out loud is appearing in Russia: whether to end the war in Ukraine at all. In a media space under tight control, the mere asking of that question is a shift worth noting.

Putin remains uncompromising - he demands full control over the Donbas, shows no remorse for the decision to invade, and continues with missile and drone strikes despite economic pressure. But around him, something is shifting. The hope that Trump would broker a peace favourable to Moscow - the so-called "spirit of Anchorage" - has evaporated. Kremlin adviser Yuri Ushakov recently even distanced himself: "I never used that term."

Why is the tone changing? Because the bill has come due. Enormous losses on the battlefield, technological backwardness, a budget deficit, a stalled economy - and a war that has already reached Russian territory through drone strikes on refineries and the Moscow region. When the war knocks on your own door, the abstract "special operation" becomes a lot more concrete.

The voices differ. Political analyst Vasily Kashin says the goal of removing the "anti-Russian government" in Kyiv is "technically unfeasible" without full occupation. Commentator Alexander Nosovich describes a divided expert community, where some believe "the worst-case scenario isn't defeat, but endless operations." Others, like lawyer Dmitry Krasnov, console themselves with history - that Russian defeats "have regularly led to reforms and, surprisingly, new victories."

But the limits of this debate are clear. One controversial article that suggested Russia consider ending the war without achieving its goals was soon deleted from the internet - readers ran into an "Error 404" message. So much for the freedom of the new discussion.

For the Balkans, which remember well the regimes that talked in one direction while reality went in another, this is a familiar moment. When a system begins to allow questions it once banned, that's rarely a sign of openness - more often it's a sign that reality has become too heavy to hide. The question isn't whether Russia has doubts; the question is how long it will allow that doubt to be spoken.
