Miscalculations, divisions marked offensive planning by U.S., Ukraine

On June 15, in a conference room at NATO headquarters in Brussels, Defense Secretary Lloyd Austin, flanked by top U.S. commanders, sat around a table with his Ukrainian counterpart, who was joined by aides from Kyiv. The room was heavy with an air of frustration.

Austin, in his deliberate baritone, asked Ukrainian Defense Minister Oleksii Reznikov about Ukraine’s decision-making in the opening days of its long-awaited counteroffensive, pressing him on why his forces weren’t using Western-supplied mine-clearing equipment to enable a larger, mechanized assault, or using smoke to conceal their advances. Despite Russia’s thick defensive lines, Austin said, the Kremlin’s troops weren’t invincible.
