Sometimes it is a distinction without a difference. This was always the Communist line--we love the people, not the government. Now if the people would just rise up and get rid of that bad government, we can have peace and harmony. In fact, we (the Communists) will help you get rid of that government.
This is a big difference. Most Poles see Russians as victims of their own government and see the Soviet atrocities as conducted to the main by people abused by their own government (except of course the KGB and UB).
