Biden administration is facing growing internal dissent over its support for Israel’s military assault on Hamas in Gaza, reflecting a wider debate in American society and a generational divide among Democrats over the issue, NBC reports.

The extraordinary scope of the dissent inside the government, including statements in open letters from government employees, goes beyond anything seen in previous administrations dating back to the 1980s, including during the Iraq War and President Donald Trump’s restrictions on travel from mainly Muslim states, former officials said.

“It’s remarkable and it’s unprecedented,” said Aaron David Miller, a senior fellow at the Carnegie Endowment for International Peace think tank who worked at the State Department from 1978 to 2003.

“I’ve never seen anything like it.”

The administration is now having to mediate its own internal version of the Israeli-Palestinian conflict, Miller said.

There is a feeling that Israel should not be able to act with “impunity,” the official said, and many foreign service officers believe that with the high civilian death toll in Gaza, U.S. aid to Israel should not remain unconditional, the official said.

U.S. diplomats in the Middle East are sending emails back to Washington saying their most levelheaded counterparts in the region are warning them that America’s reputation is being seriously damaged by its approach to the war, according to two State Department officials.
