From Responsiblestatecraft's Wikipedia page:
"During the 2022 Russian invasion of Ukraine, there were two resignations in protest at the institute's dovish response to the conflict: non-resident fellow Joseph Cirincione of Ploughshares Fund, who had raised money for Quincy, and board member Paul Eaton, a retired senior Army major officer and adviser to Democratic politicians and liberal advocacy groups. Cirincione said he "fundamentally" disagrees with Quincy experts who "completely ignore the dangers and the horrors of Russia’s invasion and occupation and focus almost exclusively on criticism of the United States, NATO, and Ukraine". Eaton said he resigned because he "supports NATO".
