Is Ukraine’s counteroffensive failing? Kyiv and its supporters worry about losing control of the narrative

Some U.S. officials privately expressed disappointment that the Ukrainians have appeared to hold back on deploying some of their most well-equipped and trained units, and that they have not necessarily applied the training principles they received. “There is a frustration that they have not used more of the combat power that they have,” one U.S. official said.

Another senior administration official said the Biden administration and U.S. allies have given Ukraine everything it requested for the counteroffensive, including 500 tanks and hundreds of armored vehicles.
