On Ukraine crisis, Biden seeks to show his mettle
America’s chaotic exit from Afghanistan last year was a made-for-TV tragedy — complete with camera-ready scenes of frantic civilians, harried US Marines and helicopters hovering over an embassy roof. Ukraine is a foreign policy conundrum of an entirely different sort. President Joe Biden’s task is to stop a war from beginning, not to end one with dignity. But even if he wards off a Russian invasion, he shouldn’t expect any ticker tape on Fifth Avenue.
