Side by side in Wiesbaden’s mission command center, American and Ukrainian officers planned Kyiv’s counteroffensives. A vast American intelligence-collection effort both guided big-picture battle strategy and funneled precise targeting information down to Ukrainian soldiers in the field.
One European intelligence chief recalled being taken aback to learn how deeply enmeshed his N.A.T.O. counterparts had become in Ukrainian operations.
But ultimately the partnership strained — and the arc of the war shifted — amid rivalries, resentments and diverging imperatives and agendas.
The Ukrainians sometimes saw the Americans as overbearing and controlling — the prototypical patronizing Americans. The Americans sometimes couldn’t understand why the Ukrainians didn’t simply accept good advice.
Where the Americans focused on measured, achievable objectives, they saw the Ukrainians as constantly grasping for the big win, the bright, shining prize. The Ukrainians, for their part, often saw the Americans as holding them back. The Ukrainians aimed to win the war outright. Even as they shared that hope, the Americans wanted to make sure the Ukrainians didn’t lose it.
the pivotal moment of the war — in mid-2023, as the Ukrainians mounted a counteroffensive to build victorious momentum after the first year’s successes — the strategy devised in Wiesbaden fell victim to the fractious internal politics of Ukraine: The president, Volodymyr Zelensky, versus his military chief (and potential electoral rival), and the military chief versus his headstrong subordinate commander. When Mr. Zelensky sided with the subordinate, the Ukrainians poured vast complements of men and resources into a finally futile campaign to recapture the devastated city of Bakhmut. Within months, the entire counteroffensive ended in stillborn failure.
