In this context a phrase "Polish concentration camps" is absurd and scientifically disqualified. @michalgornicki shared his concern about the influence of the gaffe on the perception of Poland during the Euro 2012 championship: After this, all of the European football teams that come to Poland visit only the "Polish concentration camps," this is just great
А с исторической точки зрения фраза "польские концентрационные лагеря" звучит просто абсурдно.
