Why? He's "in love with the state of Israel." How? By disdaining reason, preaching racist hate, and vilifying Israel's enemies.
In 1982, he denounced IF Stone for supporting a public appeal to help victims of Israel's lawless Beirut siege. He claimed it was about raising "money so that the PLO (could) continue to fight."
At the time, in fact, PLO respectability was growing. It pursued peace negotiations and unilaterally ceased attacks. Israeli Prime Minister Yithak Shamir admitted Israel waged war on Lebanon because of "a terrible danger....not so much a military one as a political one."
So alleged PLO threats were invented to wage war lawlessly. Before it ended, 18,000 died, mostly Lebanese and Palestinian civilians. They included thousands massacred in cold blood in the Sabra and Shatila refugee camps.
In August 1982, his TNR revisionist article titled, "Lebanese Eyewitness" said:
"Much of what you have read in the newspapers and news magazines about the war in Lebanon - and even more of what you have seen and heard on television - is simply not true."
Robert Fisk called the slaughter "one of the most shocking war crimes of the 20th century." For Peretz, murdering 18,000 innocent victims was justified. For decades, he outrageously supported Israel's worst crimes of war and against humanity without batting an eye or apologizing for lying to readers on what actually happens, why, and the consequences for innocent victims.
He also viciously attacks Israeli critics and Muslims in hate commentaries. He called the Russell Tribunal on Palestine a "kangaroo court." He accused Jimmy Carter of being "demented."
He assailed Archbishop Desmond Tutu for lying about Israeli injustice towards Palestinians. He denounced Richard Falk for calling Ayatollah Khomeini critics misguided, and saying Aerial Sharon should be indicted for his involvement in the Shabra and Shatilla massacres.
