Ujm, if a Jew’s host country is accused of misdeeds, will it be devastating to him? If someone told me that america is engaging in genocide, it won’t hurt my feelings. Russian jews (at least authentic jews) are not going to be offended if for some reason Russia is “right” and we condemn it.
Effectively telling Ukrainian yidden that they aren’t really suffering is, on the other hand, extremely offensive. Imagine someone suffering and being told “no, no…youre not really suffering; I don’t believe you, this is all a conspiracy”. Take out russia, insert Germany, and you have Holocaust denial.
