The Russian assault on Ukraine has created a surge of support for liberal interventionism in the West, prompting one of that current's most prominent exponents to suggest that a brief moment of foreign policy restraint was at an end. Not so, countered Yale historian Michael Brenes: "Restrainers are a more visible, organized bloc that at any time in recent memory." In fact, he argued, the war showed the urgency of developing a positive vision for U.S. strategic restraint - not merely opposing the errors of the hawks, but advancing alternative visions of global order.
