Answer:
' The greatest cruelties of our century have been the impersonal cruelties of remote decision...' Eric Hobsbawm, the Age of Extremes
Explanation:
I´m not sure if Holocaust really is capable of, or encouraging, positive change. To start with, etnical clensing just continuied after the Holocaust in the same way it had started the violent 20th century (Armenian genocide by the Turks), whether in Europe (Yugoslavia), Asia (Vietnam war) or Africa (Congo).
Secondly, and as Eric Hobsbawm clearly and eloquently points out, technology has made its victims invisible. The perfect organization of the holocaust by German bureaucrats (timetables of trains and the like) was possibly because it consisted of many people just doing their job unconsciously.
So only if we learn to see people at the other end of the world as real people there is a possibility of change. But our personal involvement and comprehension is becoming less and less real in a virtual world.
