A year ago, Ukrainian President Volodymyr Zelensky articulated a strategy of “bringing the war back to Russia.” “The war was brought from Russia, and it is to Russia that the war must be pushed back. They must be the ones forced into peace. They are the ones who must be pressured to ensure security,” Zelensky said in March 2025.

Since then, and ever more intensely this year, Ukraine has been pursuing a “strategic neutralization” of assets in Russia. This means scaling back the hard-fought, casualty-intensive thrusts to claw back occupied territory that have cost Ukraine so much in terms of blood and treasure, and instead embracing long-range, asymmetric warfare to degrade Russia’s economy, rupture its military manufacturing, and deflate civilian morale. This spring, there’s every sign that this strategy is bearing fruit—and perhaps even shifting the battlefield calculus in the war’s fifth, grinding year.

Almost daily, Ukraine’s new weaponry capabilities, in particular its own long-range missiles and high-precision drones, are wreaking havoc where they hit energy infrastructure, arms and explosives factories, and military command and logistics centers. On the home front, Ukraine is playing defense, killing or wounding about 35,000 Russians a month, according to Ukrainian sources, bringing some estimates of the war’s total death toll to 352,000 Russian service members.
