I see the point, but to be honest, many European countries (my own included) suffered greatly under Nazi Germany - including mass deportations and killings (but maybe sans the starving part), and yet we've forgiven the Germans. Sure, the USSR times were more recent than II WW, but I hope in years people learn to forgive Russia for the soviet times too. Keeping an "eye for an eye" attitude can get you only so far, and it's better to be friendly and work towards ensuring atrocities such like these don't happen again.
Germans went to apologize and pay retributions. Also considerable soul seeking that lasts many decades now.
Russians (there are exceptions certainly, but statistically) are proud for the oppression they did upon the neighbours and cherish it as their golden years and action plan ahead.
You do realise that in modern Russia Stalin is considered a hero and role model?
Lie. For most people in Russia Stalin is just a figure of USSR past that they do not care much about. Few people which try to bring Stalin do not have wide support and they do not make your words true.
Lie. Stalin is openly revered as an example of real leadership.
Proofs?
Friends you say? Oh, that's rich. Maybe when they give us back our national treasure, along with Basarabia and Northen Bukovina, which they took with the Molotov–Ribbentrop Pact and apologize for crushing the national identity of those regions, for starving them to death and for the mass deportations and killings, maybe then we can be friends.
But that will never happen, especially given its leadership. So until hell freezes over, they can go fuck themselves.
