The poll shows growing discontent among Americans with Israel’s war in Gaza. A Gallup poll in November found that 50 percent of Americans approved of Israel’s actions in Gaza, while 45 percent disapproved and 4 percent said they had no opinion on the war. The conflict, which has now killed more than 32,490 Palestinians, according to the Gaza Health Ministry, which does not distinguish between civilians and combatants, followed the Hamas militant group’s Oct. 7 attack in Israel that killed about 1,200 people.

Approval of the war fell among both Republicans and Democrats, although those groups remain split: 64 percent of Republicans and 18 percent of Democrats approve of Israel’s military action, according to the March poll. Such sentiments have fallen since November among adherents of both parties: 71 percent of Republicans said then that they approved of Israel’s war in Gaza, while 36 percent of Democrats said they did.

A poll conducted last month by the Pew Research Center and published last week found that opinions on the war are also split across religious lines, with 62 percent of American Jews saying Israel’s war conduct is acceptable and 5 percent of American Muslims saying so.

The Biden administration in recent weeks has expressed frustration with Israel’s conduct in the Gaza Strip. Secretary of Defense Lloyd Austin told Israeli Defense Minister Yoav Gallant in a meeting at the Pentagon on Tuesday that “in Gaza today, the number of civilian casualties is far too high, and the amount of humanitarian aid is far too low.”

The United States on Monday abstained from a United Nations Security Council vote on a resolution calling for a cease-fire in Gaza, allowing the measure to pass. The resolution — and the U.S. abstention — infuriated Israeli Prime Minister Benjamin Netanyahu, who canceled a planned visit by Israeli officials to Washington. The United States usually vetoes measures seen as unfriendly to Israel.
