He has a good column provocatively titled What Often Happens to Israel’s Critics I, picking up a Johann Hari piece on his own smearing for daring to criticize Israel. Hari:
Any attempt to describe accurately the situation for Palestinians is met like this. If you recount the pumping of sewage onto Palestinian land, "Honest Reporting" claims you are reviving the anti-Semitic myth of Jews "poisoning the wells." If you interview a woman whose baby died in 2002 because she was detained – in labour – by Israeli soldiers at a checkpoint within the West Bank, "Honest Reporting" will say you didn’t explain "the real cause": the election of Hamas in, um, 2006. And on, and on.
…[Alan] Dershowitz is a lawyer, Harvard professor and author of The Case For Israel. He sees ethnic cleansing as a trifling matter, writing: "Political solutions often require the movement of people, and such movement is not always voluntary … It is a fifth-rate issue analogous in many respects to some massive urban renewal." If a prominent American figure takes a position on Israel to the left of this, Dershowitz often takes to the airwaves to call them anti-Semites and bigots.
