These searing questions, which invaded me, which I could not help asking, do not undermine or disrespect the ceremony at the Centrale Markthal. They make the need to remember more relevant than ever, the certainty that never again should humanity witness terrible war crimes without demanding accountability, as the prosecutor of the International Criminal Court in the Hague has done. More relevant, also, because those who acclaim Hamas — a murderous, theocratic, misogynistic, oppressive organization that also massacres children and holds innocent hostages — those who share its dreams of ridding the region of its Israeli enemies, would do well to attend memorials like the one I was at on May 4 in Amsterdam.
