More Important Than Territory, Ukraine Is Taking the Battlefield Initiative

In Lyman, Kharkiv, Zhaporizhzhia, Pokrovsk and other points along the front Ukrainian forces have taken the initiative, meaning that the Russians are having to respond to their moves rather than, as has been true for much of the war since the invasion, that Ukraine has had to respond to them. 

This means Ukraine can set the time, place and nature of the fighting, which puts the Kremlin at a disadvantage. JL

Wes O'Donnell reports in Medium:
Initiative doesn’t mean attacking constantly, having more troops, or advancing everywhere at once. An army has the initiative when its actions force the opposing commander to change plans. If I attack somewhere and you have to move your reserve there, I’ve influenced your next decision. If I threaten your flank and you have to pause your offensive to protect it, I’ve gained something even if I capture very little territory. If I destroy a salient you spent six months building and force you to redesign the next phase of your campaign, the map may barely change while the operational situation changes significantly. That’s initiative.

Kremlin Setbacks Mount On Kharkiv Front

For the sixth time in recent memory, the Russians have claimed a victory in the Kharkiv region which turned out to be false, disproved by Ukrainian drones, artillery and combined arms counterattacks, often in armored vehicles. 

This is consistent with Ukrainian advances elsewhere on the front, as Russia's cumulative leadership, logistical and recruiting failures add up. JL

RFU News reports:
The Ukrainians are striking Russian deployment points before they even manage to cross the border into Ukraine. They followed Russian movements and tracked which buildings they had entered. Then, the shelling commenced. FPV drones with extended range were launched from mothership drones, to chase down Russian infantry that had managed to dismount. This is the sixth time that Russians claim to have achieved a major victory, before Ukrainians humiliate them by dismantling the Russian fantasy bit by bit. At Stepnohirsk, Uspenivka, Komar, Liman, and Kupiansk even twice, Russians suffered major defeats and extensive public backlash after overexaggerated claims of Russian advances

After Infiltrating Kostantynivka 2 Months Ago, Russians Still Stalled

Kupiansk, Mala Tokmachka, Lyman, Kostiantynivka...the list goes on...of towns and cities the Russians claim to have captured but remain in Ukrainian hands, or at least partially.

Kostiantynivka is especially significant because it was expected to be the first of Ukraine's Fortress Belt cities to fall. Russia began assaults that many believed would quickly end with Ukraine's retreat, just as they had believed that about Pokrovsk, Bakhmut and, first of all, Kyiv, way back when the invasion started. But like those earlier examples, Kostiantynivka has proved a tougher objective to crack. It still holds because the Ukrainian defense is stronger than expected, as usual, but also because the Russians can no longer summon the resources to overwhelm anything on the battlefield. And as they continue to learn across the front, infiltration does not equal occupation. So it still stands as a Ukrainian bastion. JL

Ryder Blackthorn reports in Frontline Signal:
Russia officially declared Kostyantynivka captured more than two months ago, but the battlefield didn’t get the memo. The tactical complexity inside Kostyantynivka stems directly from the failure of Moscow’s original operational plan. While Russian units successfully worked around the flanks, turning that initial infiltration into durable control remains an unfulfilled objective. There is a strict line between a tactical presence and operational control. Russian infantry entering a neighborhood does not mean the sector has been secured. Some Russian assault groups appear to have advanced faster than the logistical network required to sustain them. Russia found its way into the city's southern gateway, but has yet to prove it can stay there. 

Kremlin's Fortress Belt Plan "Significantly Disrupted' By Ukraine's Vivaldi Operation

As more comes out about Ukraine's Operation Vivaldi, it has become apparent not just that the Russians are being pushed back around Lyman - and continue to be - but that this has been going on for months, has essentially disrupted, for at least this year, the Kremlin Fortress Belt attack plan, which thus throws off Putin's entire invasion concept. JL

The Institute for the Study of War reports:
Ukraine's Operation Vivaldi has achieved the operationally-significant objective of disrupting the Russian effort to conduct a wide encirclement of Ukraine’s Fortress Belt. Ukraine’s gains thus far north of Lyman have rendered unfeasible the already-unrealistic Russian plan to encircle the Fortress Belt from the north and south. Russian forces also lost positions south of Lyman and are struggling to recapture positions within Lyman itself because of the Ukrainian advances. These Ukrainian gains were only the first phase of Operation Vivaldi and that Ukrainian forces will continue the operation. Ukrainian forces have likely made additional gains beyond what General Biletskyi has reported. The situation for Russian forces continues to deteriorate in the area, including north and south of Kolodyazi.

What It Will Take For the AI Buildout To Pay Off?

The short answer is that increased earnings won't be enough. And the reason is that the current as well as planned expenditures remain so extraordinary that mere income cannot make up the gap between projected spending and projected revenue. 

In fact, what AI will have to do is what its exuberant have promised, which is to drive the entire economy to new heights of productivity so that every enterprise, man, woman, child and robot will have more time and money to provide a return on the investment. This is, at least theoretically, possible. That there is has been little to no productivity growth so far is, to be real, discouraging. But then Silicon Valley didn't generate all that wealth by shrinking away from a challenge. JL

David Rotman reports in MIT Technology Review:
How fast will hyperscalers’ earnings will need to grow to justify their spending through 2027, when expenditures will reach nearly $1.1 trillion. The results: The AI companies will need to increase their productivity by a factor of 2.7 to break even by 2030, accounting for the cost of capital, a 15% return, and depreciation of the assets. Not impossible. But, for it to happen by 2030 “that’s a lot of growth compressed into a few years.” AI companies need to start making a lot more money. And they need to do it fast. But juicing their earnings alone still won’t be enough to sustain data-center investments for the long term. AI is going to have to create broad economic growth to justify the hyperscalers’ spending spree. For the investments to be sustainable over the next five to 10 years, we “need to see productivity gains.” (But) most economists agree that, for now, the economy-wide statistics show little or no productivity growth from AI.

Drone Not Fooled By Russian Soldier's Standing Still Like Statue

In what proved to be a vain attempt to avoid detection by a hovering Ukrainian drone, a Russian soldier on the Pokrovsk front stood stock still in hopes that the drone would not see him. It didn't work.

Nice try, though. JL

Ivan Khomenko reports in United 24:
Russian soldier on the Pokrovsk front attempted to avoid detection by remaining completely still after spotting an approaching Ukrainian FPV drone. In the footage, from Ukraine's Spartan Brigade, the Russian serviceman notices the FPV drone and immediately stops moving among the trees, apparently attempting to blend into the surrounding vegetation. The attempt did not prevent the Ukrainian drone operator from identifying him. 

Why Russia's Advance Has Slowed And Its War Has Become Unwinnable

Putin may not lose the war he started, but it is becoming increasingly apparent that he cannot win. 

Data reveal an 82% decline in Russian territory seized while in a growing number of sectors the Ukrainians are liberating more ground. And what the Kremlin has to show for this deteriorating performance is a huge increase in casualties. The result provides further evidence that Ukraine is now degrading Russia's military and that there is no prospect - even with additional Chinese and North Korean aid in addition to a Russian mobilization - that Kremlin is capable of reversing this situation. JL

The World Strategist reports:
The numbers don't lie. Russian forces seized 505.55 square kilometers in August 2025. By August 2026, that figure had shrunk to 90.35 square kilometers, an over 82% reduction. In July 2026, Russian forces averaged 353 casualties per square kilometer of territory infiltrated and a staggering 1,132 casualties per square kilometer of territory actually seized. “The heavy losses of Russian troops and equipment amid slow advances indicate that Ukrainian strikes are degrading Russian military operations on the battlefield”. The reasons for the slower Russian advances are not seasonal or temporary, but fundamental changes in the character of the war: drone dominance and ground counterattacks. There is “no indication that Russian forces will be able to accelerate their advances or restore maneuver."
