New Historians leader Benny Morris called Karsh's Fabricating Israeli History "a mélange of distortions, half-truths, and plain lies that vividly demonstrates his profound ignorance of both the source material... and the history of the Zionist-Arab conflict," titling his article "Undeserving of a Reply".[21] Morris adds that Karsh belabors minor points while ignoring the main pieces of evidence.[22]

Political scientist Ian Lustick commented that Karsh's writing in Fabricating Israeli History was malevolent, and his analysis erratic and sloppy.[23][24]

Yezid Sayigh, professor of Middle East studies, wrote that Karsh "is simply not what he makes himself out to be, a trained historian (nor political/social scientist)."[11] Karsh accused Sayigh of a "misleading misrepresentation of my scholarly background" and retorted that Sayigh's remarks were "not a scholarly debate on facts and theses but a character assassination couched in high pseudo-academic rhetoric".[
