Ukraine 2026: ISW confirms territorial gains for Kyiv – Russia loses ground

ISW / @grok / understandingwar.org

According to ISW, Ukraine has liberated approximately 973 km² so far in 2026, while Russia gained only ~148 km² net – far below its own propaganda targets. The Russian offensive in Donetsk (Pokrovsk, Lyman, Kostyantynivka) is stalling in a grinding positional war with daily infantry infiltrations. Polymarket sees a ceasefire by year-end at 72% – but military dynamics are tipping in Kyiv's favor for the first time since 2024.

Russia: Internal leadership crisis hits frontlines – Generals under pressure

@ppr_global / @Barong369 / X

Multiple X analysts report growing internal tensions in Russia's military leadership: generals are being hunted, soldier mutinies are increasing, and Putin's strategic plan for 2026 is collapsing from within according to observers. This explains below-average territorial gains despite massive resources. The destabilization could increase Moscow's willingness to negotiate in the medium term – or lead to uncontrolled escalatory steps.

NATO Copenhagen: From budget promises to capability delivery – Shoulder-to-shoulder of the 32

nato.int / azat.tv

The conference of NATO defense ministers in Copenhagen (September 18–19) marks a strategic shift: away from spending pledges, toward concrete capability development following the Ankara Summit. Admiral Cavo Dragone emphasized deterrence, innovation, and accelerated adoption of new defense technologies – including civilian infrastructure (hospitals, ports, energy supply) in military planning frameworks. New: integration of civilian resilience is no longer a secondary theater but core doctrine.

Chinese hacker group QTFY attacks NATO military and infrastructure

FBI / NSA / media.defense.gov

A joint advisory from FBI, NSA, and other partners warns of the Chinese hacker group QTFY, which is deliberately compromising NATO military systems and critical infrastructure with malicious distributed systems. This complements the known Russian OT threat landscape with a second state-sponsored attack dimension and significantly increases pressure on Western cyber defense authorities. For defense industry and critical infrastructure companies, a new priority situation emerges regarding supply-chain security.

US withdrawal from Europe: Hegseth orders force review – Burden-sharing escalates

Reuters / drillanddefense.com

US Defense Secretary Hegseth ordered a formal review of all US forces in Europe in June 2026 and sharply criticized NATO members for insufficient defense spending. Experts warn that Europe's security depends less on US troop levels than on its own development of industrial capacities and political coordination. The Ankara Summit decision and Copenhagen's focus on capability delivery are direct responses to this structural challenge.

Lagebild

In September 2026, Europe faces a multidimensional security crisis: the Ukraine war remains locked in positional warfare with slight Ukrainian territorial gains, while Russia's internal leadership crisis makes escalation risk unpredictable. In parallel, the US-Israeli war against Iran has been running for 7 months since February 2026, fundamentally destabilizing global energy supply and Middle East architecture – a ceasefire holds at 96%, but new US attacks loom according to Trump. NATO is adapting its doctrine in Copenhagen and for the first time fully integrating civilian infrastructure into military planning, while state cyber actors from Russia and China systematically attack Western critical infrastructure. The combination of conventional war, hybrid threats, and looming US force thinning in Europe raises overall risk to levels unseen since the Cold War.
