You have nothing to be ashamed of - it was not you who were driving Russians from their homes in 1944, it was not you who were throwing them away into the frozen steppes, it was them to you.
No hay nada de qué sentirse avergonzado - no eres tú el que sacó rusos de sus casas en 1944, no eres tú el que los arrojó a las estepas congeladas, fueron ellos a ti.
