Independence day in Poland. It's meant to be a celebration of the country's return to sovereignty at the end of World War One. But a rally at this year's commemoration ended in violence. Nationalists clashed with police, attacked the Russian embassy, and burned down a pro-LGBT display. But the scenes that really stunned the world were the images of red flares burning while a crowd chanted for God, honor, and fatherland. They're slogans common during neo-Nazi marches. It's left us wondering -- how can a country that suffered under the Third Reich, find itself in this kind of political climate?
