As Israel escalates its attacks on Gaza, the State Department is discouraging diplomats working on Middle East issues from making public statements suggesting the U.S. wants to see less violence. In messages circulated on Friday, State Department staff wrote that high-level officials do not want press materials to include three specific phrases: "de-escalation/ceasefire," "end to violence/bloodshed" and "restoring calm." The revelation provides a stunning signal about the Biden administration's reluctance to push for Israeli restraint as the close U.S. partner expands the offensive it launched after Hamas ... attacked Israeli communities. U.S. officials have said they expect Israel to abide by the laws of war in its operation against Hamas. But they have avoided discussion of a ceasefire, even as aid groups and some analysts have suggested that may be essential to allow civilians to flee Gaza and allow vital supplies to enter the area after Israel cut off electricity and water. U.S. President Joe Biden has repeatedly pledged to support Israel as it seeks to avenge the unprecedented Hamas assault. Yet as Israel's biggest source of diplomatic and military support, the U.S. has significant leverage in the matter of how the country chooses to seek retribution and whether Israeli Prime Minister Benjamin Netanyahu tries to limit the civilian toll of his response. Biden allies may nudge the president and his team to issue stronger calls for Netanyahu to prioritize humanitarian concerns.
