Tensions grew between the two groups. Britain — which had governed Palestine since 1922 — referred the issue to the United Nations. The U.N. General Assembly voted in 1947 to divide Palestine into two states, one Jewish and one Arab.
The partition plan was rejected by the Arab community, in part due to concerns about how much land and access to resources it would get. But the plan was embraced by the Jewish community as legal justification for the establishment of Israel.
Israel declared independence in May 1948. Five Arab nations immediately invaded the new country, prompting a major Israeli offensive and many months of fighting. That resulted in the permanent displacement of thousands of Palestinians, which some refer to as the Nakba, meaning “catastrophe” in Arabic.
Another major turning point came in 1967, with Israel’s decisive victory in the Six-Day War against Egypt, Syria and Jordan.
Israel gained territory four times its original size, taking control of the Sinai Peninsula, the Golan Heights, the West Bank, the Gaza Strip and East Jerusalem.
Those territories have been a major point of contention and peace negotiations ever since. The U.N. issued a resolution in 1967 calling for Israeli troops to withdraw from areas it captured, though the resolution’s meaning has been disputed.
That set up the current occupation of the West Bank and Gaza, which are collectively home to some 5 million Palestinians. (Israel pulled troops and settlers out of Gaza in 2005, but it’s still considered an occupied territory because the withdrawal was done without any agreement and Israel still exerts control over it.)
The two-state solution was baked into Israel’s creation but didn’t necessarily play out as planned, says Jon Alterman, director of the Middle East Program at the Center for Strategic and International Studies.
“What started off in the U.N.’s mind as a 50-50 split of Mandatory Palestine, after the 1948 war — which was initiated by the Arab armies — it was more than 50 percent for Israel. After 1967, it was 100 percent-plus for Israel,” he says. “And now Israel is, I think, the only country that’s hard to draw on a map.”
Has the two-state solution ever come close to reality?
U.S. President Bill Clinton brought Palestine Liberation Organization (PLO) leader Yasser Arafat and Israeli Prime Minister Yitzhak Rabin together in 1993 to negotiate the agreement that came to be known as the Oslo Accords.
In it, Israel officially recognized the PLO as the representative of the Palestinian people and a partner in future negotiations, and the PLO renounced terrorism and recognized Israel’s right to exist.
The deal raised expectations for a two-state solution. But it quickly began to unravel after a series of events, including a 1994 attack on a mosque in Hebron by an American Jewish settler and Rabin’s assassination in 1995 by an Israeli settler opposed to the agreement.
Almost immediately after the Oslo Accords were signed, Israel enhanced its policy of fragmenting Gaza from the West Bank and East Jerusalem, says Atalia Omer, a professor of religion, conflict and peace studies at the Keough School of Global Affairs at the University of Notre Dame.
At the same time, Israeli settlements continued to proliferate in the West Bank — on occupied land that the Palestinians hoped would be part of their state.
And that has continued in the years since. The population of Israeli settlers in the occupied West Bank, including East Jerusalem, grew from 520,000 to more than 700,000 between 2012 and 2022, according to the U.N. Office of the High Commissioner for Human Rights.
“Settlements continue to eat into Palestinian spaces,” Omer says. “And over the course of the 30 years since the Oslo Accords — signed in the White House in September 1993 — the settlements completely prevented the possibility of a contiguous sovereign Palestinian state within that two-state framework.”
What are the other obstacles?
Discussions of a two-state solution center on a number of core issues, as the Council on Foreign Relations explains.
One is how exactly the borders would be drawn. Most international diplomacy favors Israel reverting to a version of its pre-1967 borders, without a consensus on how that would account for the Palestinians living within those borders or the Jewish Israelis beyond them.
Israel has annexed the whole city of Jerusalem as its capital, while Palestinians claim East Jerusalem as the capital of their state — which makes for another logistical question.
There’s also the major question of Palestinian refugees of the wars of 1948 and 1967. The survivors and their descendants live mostly in Jordan, Lebanon and Syria and claim the right to return to Israel based on a 1948 U.N. General Assembly resolution. Israel views that right to return as a threat to its existence as a Jewish state and believes those refugees should go to the Palestinian state instead.
Security looms large, too. Israel views certain Palestinian militant groups as existential threats — including Hamas, which governs Gaza and whose founding charter called for the obliteration of Israel — and wants them to disarm. Israel wants to maintain the ability to act in Palestinian areas against security threats. Palestinians want an end to Israel’s military occupation and full control over their own security.
Both sides want recognition of their respective states by the other and the international community. Palestinians also want acknowledgment of and redress for their forced displacement, Omer says.
“There needs to be a recognition and kind of naming, and then put in place mechanisms to redress — how can Palestinians be compensated for historical injustice they experienced — and then figure out ways of respecting Jewish citizens in the space through principles of equality and democracy,” Omer says.
Where did peace negotiations stand before this war?
There has been little progress since the turn of the millennium. The collapse of the 2000 peace process fueled the Second Intifada, a major Palestinian uprising in the Israel-occupied Palestinian territories and Israel.
It ended in 2005 with some 1,000 Israelis and 3,200 Palestinians dead, along with heightened skepticism of the peace process on both sides. Those feelings seem to have prevailed in the years since, which have been marked by terrorist attacks, military raids, rocket fire, border clashes and other incidents.
