How Gaza’s genocide is reshaping U.S. domestic politics

To claim that Israel’s genocidal war in Gaza has fundamentally changed the internal politics of the United States and the wider world might be an overstatement. But what cannot be overstated is a simple fact: Israel and its policies no longer enjoy the virtually unlimited approval and support in the US that they once taken for granted. At both the local and national levels, support for Israel has weakened significantly, while across Europe, too, political attitudes toward Israel have changed in ways that would have been difficult to imagine just three years ago.

To see that change in Europe just consider the new position taken by the United Kingdom toward Israel, particularly over the occupied West Bank. In earlier September, Foreign Secretary Ed Miliband accused Israeli settler terrorists of perpetrating ethnic cleansing against Palestinians and announced new measures targeting Israel’s settlement enterprise, including sanctions and a ban on imports. Prime Minister Andy Burnham, who just two months before taking office, apologized for Labour’s initial response to the war on Gaza for being too slow to respond to Israel’s genocide. He has said Britain must put more pressure on the Israeli government and consider further sanctions. These are not the positions Britain was taking just a few years ago.

In America it is even more evident that Israel is losing the support it once enjoyed. It would have been unthinkable just three years ago that large sections of the American public would challenge their government’s traditionally unconditional support for Israel.

Opinion polls are showing a trend of negative opinion toward Israel. Last July, an Economist/YouGov poll found that 47 percent of Americans believed Israeli Prime Minister Benjamin Netanyahu was guilty of war crimes in Gaza, while 43 percent said Israel was committing genocide against Palestinians. Nearly half, 49 percent, said the US should arrest Netanyahu if he entered the country. Even more strikingly, a February 2026 Gallup poll found that 41 percent of Americans sympathized more with Palestinians in the Middle East conflict. From 2001 through 2025, Israelis had consistently enjoyed a double-digit advantage on this measure. In 2026, for the first time in Gallup’s long-running series, Palestinians moved ahead of Israelis in Americans’ sympathies.

The change is visible beyond polling booths and political rallies.

On September 24, Oscar-winning actress Susan Sarandon and Emmy-winning actress Hannah Einbinder were among more than 100 people arrested in New York during a protest against Netanyahu outside the United Nations, where demonstrators demanded an end to U.S. arms supplies to Israel.

Hollywood star Mark Ruffalo was among more than 1,800 actors, entertainers and producers, including Nicolas Gage and Emma Stone, who signed a pledge to boycott Israeli film institutions over the war. What was once largely confined to the margins of American political debate has consequently become part of mainstream public discourse.

Politically speaking, the shift is becoming increasingly visible at the grassroots level and in electoral contests across the US. One of the clearest examples is the rise of Zohran Mamdani, who defeated former New York Governor Andrew Cuomo in the Democratic mayoral primary before going on to win the general election. Cuomo had made support for Israel one of the central issues of his campaign, while Mamdani was an outspoken critic of Israel’s conduct in Gaza and a supporter of Palestinian rights, going as far as to threaten to have Israeli Prime Minister Benjamin Netanyahu arrested if he came to New York. The ability of a candidate with such positions to win in New York — home to the largest Jewish population outside Israel — was itself politically significant. It indicates even Jewish people are not supporting Israeli actions.

The same shift is visible in the growing difficulty faced by AIPAC, the most powerful pro-Israel lobby in the United States, and its affiliated groups in some Democratic primaries.

In Michigan, AIPAC and its affiliated groups spent nearly $30 million backing pro Israel Representative, Haley Stevens, against progressive candidate Abdul El-Sayed, a vocal critic of U.S. military aid to Israel. El-Sayed nevertheless won the Democratic Senate primary on August 4 by about 48.5% of the vote.

The November midterm elections will provide a much broader test of whether this change in public opinion is beginning to translate into electoral politics.

Furthermore, the shift has also begun to show itself inside Congress in ways that would have been extremely difficult to imagine only a few years ago. On July 15, the House of Representatives voted on an amendment that would have cut $3.3 billion in military aid to Israel from a broader national security spending bill. True the amendment failed but 103 Democrats and one Republican voted in favour of the cut. In other words, more than half of all House Democrats backed an effort to cut military aid to Israel — an extraordinary departure from the traditionally strong bipartisan support for Israel in Congress. The vote is significant because of the number of lawmakers prepared to break with the established position on U.S. military support for Israel. With the November midterm elections approaching, such a vote provides another indication that the political debate over Israel and U.S. support for it is no longer confined to the margins of American politics.

What has changed in the US is not simply the intensity of criticism of Israel, but the political space in which it now operates. What was once largely treated as a settled pro-Israel bipartisan consensus is increasingly being challenged by voters, activists, candidates and members of Congress. The shift is visible in opinion polls, in the streets, in Democratic primaries and even on the floor of the House of Representatives. None of this means that support for Israel has disappeared from American politics; it plainly has not. But the political consensus surrounding it is no longer what it was. The November midterm elections will show whether this change in public opinion and political activism has become a lasting force in American electoral politics or just a temporary shift.

Whatever the outcome of the midterms, however, it will be difficult for Israel to return to the position it once occupied in American public life — as a state that could count on being treated by much of American public opinion and the political establishment as virtually beyond criticism.

It will be interesting to watch whether Democrats on the left who make it into the next Congress will use foreign policy, including U.S. support for Israel, as an issue in their dealings with pro-Israel Democrats and Republicans, including the president himself.
