Longstanding bipartisan support for Israel is weakening across the political spectrum, with growing numbers of Americans questioning whether unconditional US assistance serves their interests.

“What we’re seeing in the United States is quite unprecedented,” British-Israeli analyst Daniel Levy told Anadolu.

Voters are increasingly “questioning fundamentally whether this relationship serves America, serves the American taxpayer, serves American national security,” said Levy, who heads the New York-based US/Middle East Project.

Polling reflects the widening backlash.

A March Pew Research Center survey found that 60% of US adults viewed Israel unfavorably, up from 53% in 2025 and 42% in 2022, while 59% expressed little or no confidence in Israeli prime minister Benjamin Netanyahu.

A September Marquette Law School survey found that 59% viewed Israel unfavorably and 55% believed Washington provides it with too much military aid.

Gallup recorded approval of Israel’s military campaign in Gaza at a record-low 32% in 2025, while 60% disapproved.

Meanwhile, an AP-NORC survey in June found that 31% of US adults considered Israel’s military actions in Gaza to constitute genocide.

Former Israeli prime minister Naftali Bennett acknowledged the growing problem in July, warning of a “troubling trend in public opinion, particularly among younger Americans.”

He separately said Israel is “now associated with genocide and baby killers,” just like Italy is associated with “pasta and spaghetti.”

Levy said the Israeli regime has increasingly invoked antisemitism to counter declining support and “justify its own actions,” adding that many Jewish people are “not buying this.”

The political damage is particularly visible among younger Americans.

Gallup found approval of Israel’s military operations at just 9% among adults aged 18 to 34, while Harvard University’s Spring 2026 Youth Poll found that 46% of Americans aged 18 to 29 viewed ties with Israel as a burden, compared with 16% who saw them as a benefit.

The backlash has also reached the Republican Party, where 57% of Republicans aged 18 to 49 viewed Israel unfavorably, according to Pew.

US Vice President JD Vance has criticized Israeli officials, while Tucker Carlson accused Trump of becoming a “hostage” under Netanyahu’s “total control.”

The shift has also complicated traditional pro-Israel lobbying, with Republican Senate nominee Mike Rogers asking AIPAC not to campaign openly on his behalf.

“Having the endorsement of the Israel lobby has gone from being a blessing for the candidate who is endorsed to a curse,” Levy said.

Beyond Netanyahu, Levy argued that the crisis is structural because no major Israeli political faction is addressing “Palestinian statehood, ending occupation, withdrawing, ending settlements.”

He warned that replacing Netanyahu could provide Washington with only a temporary political reprieve while leaving the underlying policies intact.

“Israeli extremism is going to boomerang very harshly one day,” he said.
