At a major NATO summit in Madrid last year, U.S. President Joe Biden vowed to support U.S. allies and Ukraine against the Russian invasion for “as long as it takes.”
That line has come to define the U.S. policy on Europe under Biden, an avowed transatlanticist and longtime supporter of a democratic Ukraine. But as U.S. attention shifts to a new era of global competition with China—and a contentious presidential election in 2024—many Europeans are quietly beginning to wonder whether Washington’s “as long as it takes” strategy will outlast Biden.
