The National Socialist German Workers' Party (Nationalsozialistische Deutsche Arbeiterpartei)
Commonly referred to in English as the Nazi Party.
Being that socialist governments killed well over 120 million of their own people throughout the 20th century I am always stunned that Australian university students and the Marxist Greens keep preaching that socialism is more noble and preferable than the capitalism that built the greatest and most equitable civilisations in human history.
