For decades, Israel has counted on a small pool of Western allies for military, diplomatic, and political support. But almost two years into the Gaza war, Israel’s allies are showing signs of fatigue and dissent. What started as a sympathy wave following the October 7 Hamas attacks has now increasingly turned into bitter denunciation, sanctions, and even outreach for bestowing legitimacy upon a Palestinian state. Israel currently is experiencing a degree of diplomatic isolation that would have been unimaginable just a few years ago.
Sympathy to Sanctions: How the Gaza War Isolates Israel Allies
Rapidly, after Hamas’s attack, Western governments were lining up to support Israel’s right of self-defense. But as the war in Gaza wore on—with tens of thousands of civilians killed, food reserves running low, and entire neighborhoods reduced to rubble—the mood shifted. The humanitarian disaster made the allies wonder if Israel’s tactics had crossed the threshold from defense to much more devastating.
In Europe, the shift has been abrupt. The UK Labour government of Keir Starmer cancelled trade negotiations with Israel and sanctioned West Bank settlers. Germany prohibited the export of weapons destined for use in Gaza, despite being Israel’s most steadfast friend. This is a drastic change from its traditional Staatsräson. France followed suit, declaring that it would recognize Palestine at the UN
America’s Divided Support
Even in the United States—the keystone of Israeli security—the political winds are shifting. Despite the Biden administration and its eventual replacement still promising “unwavering support,” fissures are appearing. A scathing report written by Democratic Senators Chris Van Hollen and Jeff Merkley rebuked Israel for “using food as a weapon of war” and implicated Washington in complicity by providing the weapons that allow it.

Public opinion is on their side. Isolation of Israel’s military campaign by America’s voters, especially among Democrats and the young vote, has been achieved. 9% of Americans aged below 35 years are in favor of the Gaza attack. That change over a generation implies American support, previously automatic, potentially conditional in the future.
The Legal and Moral Reckoning
Apart from politics, Israel is also fighting a record number of legal cases. The UN Commission of Inquiry charged Israel with genocide, stating that its actions in Gaza constitute four out of the five “genocidal acts” codified in international law. The International Criminal Court has even issued arrest warrants against Prime Minister Benjamin Netanyahu and former Defense Minister Yoav Gallant, limiting their freedom of movement.
To Israel, these verdicts might appear to be partisan or insensitive, but they give legitimacy to sanctions diplomatically and add to its diplomatic troubles. Briefly, the case is no longer political—it is moral and legal.
Civil Society and the Street
Pressure is not just emanating from parliaments and courts. Globally, civil society has been mobilized to a degree not witnessed since the anti-apartheid campaign of the 1980s. The Boycott, Divestment, and Sanctions (BDS) movement has also gained renewed momentum, aiming at firms and institutions that have connections with Israel. At a cultural level, many thousands of artists and filmmakers have called for boycotts, making explicit the comparison between Gaza and apartheid South Africa.
These actions, spearheaded by a younger, more connected, and more global cohort, are shifting perceptions of Israel—not as a beleaguered democracy, but as collective punishment being exacted.
Israel’s policy of “Super-Sparta” response
Confronted with expanding isolation, Netanyahu has begun to prepare Israelis for a world with no reliable friends. He has addressed frankly making Israel a “super-Sparta,” an economically and militarily more independent state, less reliant on international validation or commerce. This shift toward economic and military independence is not an effort to regain friends but a recognition of permanent distance.

But it is expensive. Critics within Israel maintain that it could bring economic devastation, heighten tensions in the area, and leave Israel more diplomatically exposed.
A New Era of Isolation
Not only reconfigured the battlefield but also Israel’s place in the world. The decline of support throughout Europe, the generational gap in the U.S., the snowballing of legal condemnations, and the flowering of grassroots boycotts all indicate a structural shift.
What had long been a pillar of coalitions is now a precarious scaffolding, and Israel’s bet on military strength is being covered in the terms of global legitimacy. The longer the war continues, the deeper this isolation will cut—and the more difficult it will become for Israel to restore the confidence of its allies.
