America is following an “arsenal of democracy” strategy in Ukraine: It has avoided direct intervention against the Russian invaders, while working with allies and partners to provide the Kyiv government with money and guns.
That strategy, reminiscent of U.S. support for Britain in 1940-41, has worked wonders. Yet as the war reaches a critical stage, with the Russians preparing to consolidate their grip on eastern Ukraine, the arsenal of democracy is being depleted.
That could cause a fatal shortfall for Ukrainian forces in this conflict, and it is revealing American weaknesses that could be laid bare in the next great-power fight.
