What did charlie chaplin's film the great dictator draw attention to?

It was about the cruelty and anti-Semitism in Nazi Germany.  Though the film used a fictional country it nonetheless represented the Nazi Germany especially since it also persecuted the Jews.  It also showed that not only Jews were targeted but those who opposed the regime’s policy were also arrested.  It showed the plight of the Jews who also had to flee to other countries to survive.  Many were herded to concentration camps where they died while others survived and were liberated by allied troops.
