It should be enough that students are taught that their countries did bad things as well as good. There is no need to go into every case where a country has done wrong throughout its history. While the use of comfort women was wrong and tragic there is no reason why this should be used as an example of the suffering caused by Japanese imperialism. Students could equally be taught that Japans actions were wrong through highlighting the treatment of Prisoners of War or by showing that it was Japanese aggression that lead to war after war.
