It's shoddy and disreputable. Like Bernard Lewis and other pro-Israeli/imperial hardliners, he prioritizes lies, not truth. He defends the indefensible.
He's intellectually dishonest. He omits what's too disturbing to reveal. He justifies atrocities instead of condemning them. He claims Zionists had a divine right to create a Jewish state in Palestine.
He calls Islam problematic. It doesn't value human life like the West, he claims. It abhors "freedom, democracy, openness and creativity."
If Islamic states get nuclear, chemical, and/or biological weapons they'll "use them." If able, they'll "commit genocide."
He shames his academic credentials. His credibility is sorely lacking. Rancor and vindictiveness substitute for good sense. He's unapologetic about Israel's worst crimes.
He blames Arabs, not Jews. He elevates revisionist history to a higher level. It doesn't rise to the level of bad fiction. He distinguishes between good and bad genocide. He calls it a legitimate political tool.
He teaches Middle East studies at Ben-Gurion University of the Negev. He's one of a number of New Historians. He never met an Arab he didn't despise. He believes Jews are God's chosen people.
He writes propaganda, not history. He teaches this stuff to students. They're best advised to avoid him.
