KYIV, Ukraine (AP) — The head of U.S. intelligence says Russia’s war against Ukraine is running at a “reduced tempo” and suggests Ukrainian forces may have the upper hand in coming months. Avril Haines said Russian President Vladimir Putin “is becoming more informed of the challenges that the military faces in Russia.” But she said it’s unclear whether he has a “full picture” of the challenges. She said her team expects that both sides will look to refit, resupply, and reconstitute for a possible Ukrainian counter-offensive in the spring. In recent weeks, Russia’s military focus has been on striking Ukrainian infrastructure and pressing an offensive in the east, near the town of Bakhmut.
