I'm inclined to wonder whether this may be an official leak; inoculation, aimed at the feeble consciences of Dem centrists. i.e. "Oh, so what we say is monstrous, what we do is worse, but at least what we think is okay."
The memo has two key requests: that the U.S. support a ceasefire, and that it balance its private and public messaging toward Israel, including airing criticisms of Israeli military tactics and treatment of Palestinians that the U.S. generally prefers to keep private.
The gap between America’s private and public messaging “contributes to regional public perceptions that the United States is a biased and dishonest actor, which at best does not advance, and at worst harms, U.S. interests worldwide,” the document states.
“We must publicly criticize Israel’s violations of international norms such as failure to limit offensive operations to legitimate military targets,” the message also states. “When Israel supports settler violence and illegal land seizures or employs excessive use of force against Palestinians, we must communicate publicly that this goes against our American values so that Israel does not act with impunity.”
