The approval of U.S. aid to Ukraine, long overdue and needlessly controversial, is a major milestone. But a milestone on the way to what? The money, or the hardware it will pay for, is desperately needed to keep the Ukrainian military in the fight, to protect Ukraine’s people and infrastructure from Russia’s aerial onslaught, and to keep grinding down the Russian military machine. But a lot has happened in the eight months it took Congress to act. The key question that needs an answer now is: what are Ukraine’s war aims and strategy to achieve them? As serious doubts about the viability of Kyiv’s current strategy are being raised, Ukraine and—just as important—its allies on both sides of the Atlantic must address this dilemma.
