Opinion | Ukraine Takes the Offensive

Ukraine’s counter-offensive against invading Russian forces is an important turn in the war, though not without peril as Vladimir Putin calculates how to respond. Western leaders have to be prepared that he will use nuclear weapons, or attempt to involve NATO directly in the conflict.

In less than a week, Ukrainian forces have retaken some three thousand square kilometers from the Russian invaders. That’s more Ukrainian territory than Russia has seized since April. “The Ukrainian counteroffensive in Kharkiv Oblast is routing Russian forces and collapsing Russia’s northern Donbas axis,” says the Institute for the Study of War, which has ably tracked the conflict.
