The Iran conflict and the potential collapse of the ‘Greater Israel’ vision

A prolonged or costly war with Iran risks further erosion. Arab states prioritizing stability may view an emboldened, expansionist Israel as a greater threat than Iran's weakened position. Israel could face a future as a smaller, more isolated state, which may remain militarily strong but diplomatically constrained, economically strained by boycotts and regional hostility.

Inside Israel, divisions are stark. While annexation sentiment exists on the right, especially for the West Bank. Broader public support for endless conflict or maximalist goals is limited. Many Israelis prioritize security, economy, and normalcy over ideological expansion. Netanyahu's coalition has relied on far-right partners, but polls show fatigue, polarization, and questions about leadership.

Israel as a path to prosperity without expansion

Critics argue Israel has been the primary obstacle to regional peace through settlement expansion, occupation policies, and rejection of comprehensive deals addressing Palestinian statehood. Supporters counter that Palestinian rejectionism, terrorism (Hamas, Hezbollah), and Iranian-backed rejection of Israel's existence are the real barriers. Wars in 1948, 1967, 1973, intifadas, and ongoing rocket attacks shaped a security-first doctrine.

The thesis here is that clinging to Greater Israel designs perpetuates a cycle: perpetual conflict, isolation, and opportunity costs. An Israel that formally or de facto abandons maximalist territorial ambitions, focusing on defensible borders, technological/economic strength, and genuine two-state or confederation compromises could thrive. Normalized relations with a broader Arab world including Saudi Arabia, and the broader Sunni states could unlock trade, tourism, and security pacts against shared threats. A smaller, secure, prosperous Israel integrated regionally would likely enjoy greater long-term viability than one pursuing biblical maximalism amid demographic, diplomatic, and military strain.

The Iran conflicts of 2025–2026 may accelerate this reckoning. With U.S. support not unlimited, global opinion adverse, Arab normalization stalled, and internal Israeli debates intensifying, the vision of Greater Israel faces formidable headwinds. Whether it fails outright depends on Israeli choices, either to double down amid isolation, or pivot toward pragmatic security and integration.

A post-expansionist Israel need not be diminished. It could model success as a high-tech, culturally vibrant nation at peace with neighbors, proving that true strength lies in prosperity and acceptance rather than contested land. The coming years will test which path prevails.

In the wake of Iran's recent missile barrages and the intense exchanges of 2025–2026, a striking development has emerged: the United States appeared to step back from fully committing to Israel's defense in ways that once defined their alliance. While Washington has provided intelligence, defensive support, and conducted its own strikes on Iranian nuclear sites, reports and statements suggested limits on direct involvement during certain phases of Iranian retaliation. This perceived distancing amid other domestic U.S. priorities and war fatigue with the mid-term elections coming up has left Israel more exposed than in previous confrontations.

This moment arrives as global public opinion has soured dramatically on Israel's military campaigns in Gaza, Lebanon, and against so-called Iranian proxies. Polls across many countries show unfavorable views of Israel reaching historic highs. Protests, boycotts, and diplomatic isolation have intensified. Even within Israel, Netanyahu faces deep polarization, with approval ratings hovering around 40% and significant segments of the public questioning prolonged conflicts.

These pressures in a nation with competing narratives raise a pivotal question: Could the Iran war mark the beginning of the end for the so-called "Greater Israel Project"?

What Is "Greater Israel"?

The concept of Eretz Yisrael HaShlema ("the Whole Land of Israel") has biblical, historical, and political layers. It is not a single, universally agreed-upon policy but a spectrum of aspirations often invoked by religious Zionists, revisionist thinkers, and right-wing politicians.

Biblically, it draws from passages like Genesis 15:18–21, describing a covenant with Abraham promising land "from the river of Egypt to the great river, the Euphrates." Interpretations vary: some see it as a maximalist vision encompassing parts or all of modern Egypt ( the Nile to Brook of Egypt/Sinai), Israel/Palestine, Lebanon, Syria, Jordan, and into Iraq. Others limit it to the area "between the Sea and the Jordan River" as essentially Israel proper plus the West Bank (Judea and Samaria), Gaza, and sometimes the Golan Heights.

From Israel's formation

Pre-1948 Zionism:Theodor Herzl, founder of modern Zionism, focused primarily on establishing a Jewish homeland in Palestine amid European antisemitism. Some early discussions referenced broader areas "from the Brook of Egypt to the Euphrates" in brainstorming sessions, but these were not core platforms. Revisionists like Ze'ev Jabotinsky advocated for a Jewish state on both banks of the Jordan, influencing groups like Betar. The 1919 Paris Peace Conference saw Zionist proposals for expanded borders, but the 1922 Mandate for Palestine already separated Transjordan.
