RAMALLAH, Occupied West Bank — A wartime opinion poll among Palestinians published Wednesday shows a rise in support for Hamas, which appears to have ticked up even in the devastated Gaza Strip, and an overwhelming rejection of Western-backed President Mahmoud Abbas, with nearly 90 percent saying he must resign.

The findings by a Palestinian pollster signal more difficulties ahead for the Biden administration’s postwar vision for Gaza and raise questions about Israel’s stated goal of ending Hamas’ military and governing capabilities.

Washington has called for the West Bank-based Palestinian Authority, currently led by Abbas, to eventually assume control of Gaza and run both territories as a precursor to statehood. U.S. officials have said the PA must be revitalized, without letting on whether this would mean leadership changes.

The PA administers pockets of the Israeli-occupied West Bank and governed Gaza until a takeover by the Hamas group in 2007. The Palestinians have not held elections since 2006 when Hamas won a parliamentary majority.

Israeli Prime Minister Benjamin Netanyahu, who leads the most right-wing government in Israel’s history, has soundly rejected any role for the PA in Gaza and insists Israel must retain open-ended security control there.

Arab allies of the U.S. have said they’ll only get involved in post-war reconstruction if there’s a credible push toward a two-state solution, which is unlikely under the Netanyahu government dominated by opponents of Palestinian statehood.

With survey results indicating a further erosion of the PA’s legitimacy, at a time when there’s no apparent path toward restarting credible negotiations on Palestinian statehood, the default for postwar Gaza is an open-ended Israeli occupation, pollster Khalil Shikaki said.

“Israel is stuck in Gaza,” Shikaki told The Associated Press ahead of the publication of the survey’s results by his Palestinian Center for Policy and Survey Research (PCPSR). “Maybe the next (Israeli) government will decide that Netanyahu is not right in putting all these conditions, and they might decide to withdraw unilaterally from Gaza. But the default for the future, for Israel and Gaza, is that Israel is in full reoccupation of Gaza.”

The survey was conducted from Nov. 22 to Dec. 2 among 1,231 people in the West Bank and Gaza and had an error margin of 4 percentage points. In Gaza, poll workers conducted 481 in-person interviews during a weeklong ceasefire that ended Dec. 1.

Despite the devastation, 57 percent of respondents in Gaza and 82 percent in the West Bank believe Hamas was correct in launching the October attack, the poll indicated. A large majority believed Hamas’ claims that it acted to defend a major Islamic shrine in Jerusalem against Jewish extremists and win the release of Palestinian prisoners. Only 10 percent said they believed Hamas has committed war crimes, with a large majority saying they did not see videos showing the militants committing atrocities.

Overall, 88 percent want Abbas to resign, up by 10 percentage points from three months ago. In the West Bank, 92 percent called for the resignation of the octogenarian who has presided over an administration widely seen as corrupt, autocratic and ineffective.

The poll also signaled widespread frustration with the international community, particularly the United States, key European countries and even the United Nations, which has pushed for an immediate humanitarian cease-fire in Gaza.

The poll found that 44 percent of Gazans say they have enough food and water for a day or two, and 56 percent say that they do not. Almost two-thirds of Gazan respondents — 64 percent — said a member of their family had been killed or injured in the war.
