During his entire tenure as owner of "The New Republic" Peretz repeatedly has used the magazine's editorial pages of to attack and marginalize individuals whom he perceives as enemies of Israel, among them even many mainstream Israeli politicians and activists whom he disagreed with.—"sometimes we attack people unfairly" according to his close friend and TNR literary editor Leon Wieseltier. For example, Peretz attacked the late I. F. Stone, after the journalist signed a public appeal for the provision of water and medical supplies for siege victims trapped in West Beirut during the 1982 Israeli Siege of Beirut: Peretz editorialized, "So this is what I. F. Stone has come to, asking his admirers to put up money so that the PLO can continue to fight." In an editorial titled "Blacklisted", Peretz claimed during the first Persian Gulf War in 1991 that he was "the only writer on the Middle East not invited by PBS or NPR to speak about the Gulf."
