There were Jews at Buchenwald but there were more non-Jews. Obviously the largest single group of people who died in Nazi concentration camps were Jewish, but it tends to be forgotten how many Roma, Slaves, gays, Communists, resistance fighters etc. etc. were also killed. It is important to remember the Jewish victims, but equally important to remember the others. And certainly the Holocaust should never be used as a justification for right-wing Israeli policies of settling someone else's land and oppressing their people.
