The slashing of the portrait of Lord Balfour at Trinity College, Cambridge, is a shocking development. Not since the Taliban destroyed the Bamiyan Buddhas in 2001 have we seen such an act. The destruction of the portrait of Balfour was especially shocking, given the antisemitism that has engulfed Britain and emerged at the center of the war against the Jewish state, in the creation of which Balfour played such a prescient part.
