Ukraine's top general wanted a bold counteroffensive a year earlier that the US thought was too risky. It might have reshaped the war.

• Ukraine and the US disagreed on when and where the counteroffensive against Russia should begin.
• A new book details Zaluzhny's plan for a bold move in 2022.
• If Ukraine had hit Zaporizhzhia then, the war may have looked very different now.

Ukraine's forces slammed against stiff Russian defenses in southern Ukraine this summer, and ultimately, the counteroffensive failed. Unable to get the US onboard earlier, the move in a critical sector of southern Ukraine came a year later than when the country's top general first wanted to make it, a new book reports.

Had it come when he wanted, it might have reshaped the war, for better or worse.
