"As the above suggests, there are significant disagreements within the U.S. left as to whether the United States should send arms to Ukraine. These differences reflect divergent opinions on a diversity of issues related to politics, international order, and, in the final analysis, history. These differences will probably continue to divide the left into the foreseeable future.

Nonetheless, if U.S. leftists approach each other in an honest and open matter, they will hopefully be able to reach some sort of consensus about how they should relate to each other, their country, and U.S. foreign policy in a moment that lacks a leftist organization able to speak on behalf of the “left” as a whole. It is important that they do so, as the left will serve as a core part of the restrainer community for years to come."
