For sure, countries need to look inward and start digesting that many people ate the onion in the first half of the 40s. Not because we need justice for the deaths of local minorities commited by nationals, but because this type of behaviour causes great trauma not just for the victims, but the aggressors. They pass this trauma down and it remains alive in current generations. It usually doesn't even manifest itself as outright racism, just lots of anger issues in general (I guess this part is anecdotal).

All that being said, fuck Russia for bringing this up now. They went in to Ukraine under the flag of denazification. But Latvia is in Nato, so I don't really see this as a cassus beli, but more of sowing division in EU.
