Regardless of the sourcing, it's important to have open eyes about these things. While don't think many outside of Lemmygrad would argue that there isn't a clear moral difference between the defenders and aggressors in this war (and Prigozhin didn't exactly name his organization the Wagner Group out of a deep artistic appreciation for German opera, either), Ukraine has also been willing to take help from unsavory groups, particularly in the original Azov Brigade and the RVC. I won't condemn Ukrainian leadership for engaging in realpolitik while fighting for their nation's right to exist, but they and their Western allies all need to be careful that fascist elements within Ukraine don't get the opportunity to leverage the war for greater power and influence.
