With Russian attacks escalating and warnings about a possible new invasion from the north growing louder, Ukraine is shifting to a ring defense around Kyiv - a strategy that no longer sees the front as a line, but as a perimeter. This was confirmed by Oleksiy Danchyn, head of Kyiv's military administration, who announced a plan that goes well beyond classical fortifications.

A ring defense is a different discipline from what the public associates with trenches and anti-tank obstacles. Forces are deployed across the entire perimeter of the defended zone - not along a single axis of attack - with firing positions covering multiple directions at once. Reserves stay centrally placed, ready for rapid movement to breakthrough points. It's a complex operational system that demands discipline, coordination and significant human resources.

The overall framework isn't just about fortifications. According to Danchyn, the plans also cover mobilization of local communities, territorial defense forces, and protection of critical infrastructure - bridges, thermal power plants, command centers, logistics hubs, energy capacities. The northern direction, toward Belarus, gets particular attention, as it's considered the most vulnerable corridor toward the capital.

Setting up this kind of defense signals one thing: Ukraine's military leadership no longer believes the war will end soon. When an entire capital is preparing for a possible siege at a level that means several months of defense, this isn't the scenario of people expecting a ceasefire soon. And it isn't the scenario of people expecting significant additional support from the West - at least not in a short-term frame.

For a Balkan perspective, the lesson is simple. When a nation has to build fortifications around its own capital - it means all guarantees, agreements and alliances have limits. It also means the building campaigns from the 1990s that Balkan countries remember are now being repeated, but in a digital and satellite era. The history of the Balkans shows what happens when a country isn't ready to defend itself. Ukraine doesn't want to be another such story.
