- The decades-long conflict between Israelis and Palestinians is rooted in competing claims to the Holy Land, and includes disputes over borders, Jerusalem, security, and Palestinian refugees.
- The United States has long sought to broker a diplomatic solution to the conflict that would result in two states.
- Many analysts believe the Trump Administration’s interventions have made this outcome less likely.
Israelis and Palestinians have clashed over claims to the Holy Land for decades, a conflict that has long been one of the world’s most intractable. Although the United States is a strong supporter of Israel, it has traditionally tried to advance a diplomatic solution that would reconcile the competing claims of the two parties.
Multiple U.S. administrations have proposed road maps for a peace process that would result in two states, one Israeli and one Palestinian. However, many critics say prospects for a so-called two-state solution have dimmed with President Donald J. Trump’s controversial policy pivots on core components of the conflict, including Jerusalem’s status and Israeli settlements in the West Bank.
What is the Israeli-Palestinian conflict about?
The Israeli-Palestinian conflict is rooted in a century-long territorial dispute over the Holy Land, a Middle Eastern region with great religious and historical significance to Christians, Jews, and Muslims.
Increasing numbers of Jews began moving to Ottoman Palestine—a predominately Arab region—following the 1896 publication of Theodor Herzl’s The Jewish State, which promoted the idea of a haven for Jews in their ancient homeland to escape anti-Semitism in Europe. The migration accelerated after the Holocaust of World War II, in which Nazi Germany killed six million Jews.
In 1947, after years of Arab-Jewish violence, the UN General Assembly voted for the establishment of two states in Palestine, one Jewish and the other Arab. Shortly after, the Jewish community in Palestine declared Israel an independent state, prompting hundreds of thousands more Jews to emigrate, and precipitating a war launched by neighboring Arab states.
For their part, Palestinian Arabs say Jews have usurped their ancestral homeland with help from Western powers, including the United States and the United Kingdom. They refer to Israel’s establishment and its defeat of allied Arab armies in the 1948 war as the Nakba, or catastrophe, which the United Nations estimated uprooted more than seven hundred thousand Palestinians.
In the decades since, the Israeli-Palestinian dispute has continually flared into conflict, including multistate wars, armed uprisings (intifadas), and terrorist acts. A major turning point was the 1967 Six-Day War, which culminated in Israel’s occupation of East Jerusalem, the West Bank, and Gaza. In its aftermath, the UN Security Council adopted Resolution 242, which called for Israel to withdraw from occupied lands to secure and recognize borders in exchange for peace. The resolution lacked details, but nonetheless was a milestone, becoming the basis for future diplomacy to end the Arab-Israeli conflict.
Today, the region is home to some two million Palestinians in the Gaza Strip and three million in the West Bank. Although most of Israel’s 9.1 million residents are Jewish, there are around two million Arab citizens. International diplomatic efforts to broker a political settlement have made limited headway. More recent U.S.-led diplomacy has focused on resolving several core issues:
Borders. The notion of having two separate states, one Israeli and the other Palestinian, commonly referred to as the two-state solution, has had significant international support for decades. It would establish a Palestinian state that includes most of the West Bank—with land swaps to compensate it for Israel’s absorption of some Jewish settlements there—and Gaza, which Israel unilaterally withdrew from in 2005. Most international diplomacy promoting a two-state solution favors Israel’s reverting to a version of its pre-1967 borders, but there is no consensus on how doing so could account for Palestinians within those borders and Jewish Israelis living beyond them.
Jerusalem. The disputed city straddles the border of Israel and the West Bank. Israel has annexed the whole city as its capital; the Palestinians claim East Jerusalem for the capital of their state. A two-state solution would require a Palestinian capital in East Jerusalem.
Refugees. The wars in 1948 and 1967 created some one million Palestinian refugees. The survivors and their descendants, mostly living in Jordan, Lebanon, and Syria, claim the right to return to Israel, as supported by a 1948 UN General Assembly resolution. Debate continues on whether survivors’ descendants should also be considered refugees with that right. Israel sees the right to return as a threat to its existence as a Jewish state, and believes the refugees should go to the Palestinian state that would be created as part of a two-state solution.
Security. Israel views some Palestinian militant groups as existential threats [PDF], particularly Hamas, the Islamist organization that governs Gaza and has vowed to destroy Israel. Its suicide bombings and rocket attacks usually target Israeli civilians. Israel wants these groups to disarm and the Palestinian state to be demilitarized, but accepts that Palestinians should have a strong police force. The Palestinians seek an end to Israel’s military occupation and want full control over their own security, but accept limitations on their arms. Israel wants to maintain the ability to act in Palestinian territory against threats to its security.
Mutual recognition. Each side seeks recognition of its state by the other, as well as the international community. Most Israeli Jews want to see Israel recognized as a Jewish state, while Palestinians want Israel to acknowledge their forced displacement under the Nakba.
End of conflict. Both sides seek a peace agreement that would end their conflict and honor the claims of each side, and lead to peace and normalization of Israel’s relations with all Arab states, as provided for in the Arab League’s Arab Peace Initiative.
What are U.S. interests in the dispute?
The Middle East has long been of central importance to the United States as successive administrations pursued a broad set of interrelated goals including securing vital energy resources, staving off Soviet and Iranian influence, ensuring the survival and security of Israel and Arab allies, countering terrorism, promoting democracy, and reducing refugee flows. Correspondingly, the United States has sought to resolve the Israeli-Palestinian conflict, which has been a major driver of regional dynamics, with an eye toward obtaining these strategic objectives while balancing its support for Israel and pushing for broader regional stability.
At the same time, the dispute has been a core concern of the American Jewish community and Christian Evangelicals, both strong supporters of Israel.
However, some experts say U.S. interest in resolving the conflict has waned in recent years. After the start of the Arab Spring in 2011, other regional conflicts, such as wars in Syria and Yemen, Iran’s push for dominance in the region, and terrorist groups such as al-Qaeda and the self-proclaimed Islamic State posed more immediate threats to U.S. interests. Additionally, U.S. relations with Iran and the Arab Gulf states no longer seem to hinge on Israeli-Palestinian issues, making the conflict even less of a priority, says CFR’s Philip H. Gordon, who worked on Middle East peace negotiations at the White House during the Barack Obama administration.
U.S. interest in the greater Middle East also faded as other regions gained priority, as highlighted by the Obama administration’s “Pivot to Asia.” With its significant policy changes, the Trump administration is aiming to resolve the conflict in Israel’s favor and impose a solution on the Palestinians.
How has the U.S. been involved in the conflict?
The United States has been a central player in the Israeli-Palestinian conflict for more than half a century. It became involved shortly after World War II, joining the United Kingdom in a 1946 inquiry [PDF] that recommended one hundred thousand Holocaust survivors relocate to Palestine, which would be neither a Jewish nor an Arab state. The United States then became the first country to recognize Israel as a sovereign nation in 1948.
After the 1967 Six-Day War, the United States attempted to mediate the broader Arab-Israeli conflict along with Britain, France, Russia, and the United Nations. However, it was the 1973 war, in which Israel struggled early on to defend itself against invading Egyptian and Syrian forces, that compelled the United States to take the lead in future diplomacy. Although Israel won the conflict militarily, the Arab powers delivered a major psychological blow.
The war was also a major turning point for U.S. foreign policy in that it prompted Arab oil producers to impose a harmful oil embargo on the United States, and it brought the United States—which supported Israel—and the Soviet Union—which armed Egypt and Syria—close to a nuclear confrontation after a period of détente. The war also proved a boon for the Palestinian cause, with the Arab League recognizing the Palestine Liberation Organization (PLO) as the “sole legitimate representative of the Palestinian people” in 1974.
In the months after the fighting, U.S. Secretary of State Henry Kissinger served as the principal intermediary between the Arab states and Israel. His shuttle diplomacy among Middle East capitals in 1974 and 1975 helped de-escalate the war and disentangle the combatants.
In 1978, U.S. President Jimmy Carter hosted the Camp David peace talks between Israel and Egypt, which produced two frameworks that would lay a foundation for future Mideast diplomacy. The first called for talks involving Egypt, Israel, Jordan, and the Palestinians about Palestinian self-rule in Gaza and the West Bank. The second called for a peace treaty between Egypt and Israel, which the two governments signed in 1979 at the White House. Though Jordan was also a party in the 1973 war, it did not join the talks, fearing condemnation from other Arab nations. A separate Israel-Jordan peace treaty was signed in 1994.
Although the United States was left out of negotiating the 1993 Oslo Peace Accords—under which Palestinian leaders recognized Israel’s right to exist, and Israel recognized Palestinian autonomy in Gaza and the West Bank—the disputing parties signed the final agreement at the White House. The United States and the Bill Clinton administration played a larger role in 1998, when it sponsored negotiations between Israel and the PLO that led to the Clinton Parameters for the establishment of a two-state solution. Since then, successive administrations have proposed their own plans for a two-state solution: George W. Bush’s Road Map to Peace, Secretary of State John Kerry’s Six Principles, and Trump’s Peace to Prosperity.
While trying to broker a deal between the parties, the United States has shielded Israel from international criticism, which some say has hindered diplomacy to resolve the conflict. Since 1970, the United States has used its veto power as a permanent member of the UN Security Council to block resolutions censuring Israel dozens of times because it sees the United Nations as a forum that is biased against Israel. Since 1980, the United States has only once allowed the Security Council to condemn Israel for its settlement construction, in late 2016, when the outgoing Obama administration abstained from a vote on the matter.
Many analysts say Trump has abandoned the role of honest broker between Israel and the Palestinians and adopted a firmly pro-Israel stance. In August 2020, the Trump administration mediated an agreement between Israel and the United Arab Emirates, known as the Abraham Accord, in which the two countries pledged to begin normalizing ties. A month later, Bahrain and Israel announced a similar U.S.-brokered deal.
What is the U.S. position on Palestinian statehood?
For nearly two decades, the United States has explicitly supported a two-state solution that calls for separate Israeli and Palestinian states with borders resembling those that existed before the 1967 war, which include the Gaza Strip, the West Bank, and parts of East Jerusalem. The Clinton Parameters provided the outlines for the establishment of a Palestinian state and the resolution of the other final status issues. George W. Bush became the first U.S. president to publicly endorse a Palestinian state, which was represented in the 2003 Road Map for Peace plan put forth by the United States, the European Union, Russia, and the United Nations. The Obama administration also tried to advance a two-state solution, but talks collapsed in 2014 over disagreements on settlements, the release of Palestinian prisoners, and other issues. In 2016, Secretary Kerry outlined principles for a two-state solution based on those final status talks.
Trump’s plan, dubbed Peace to Prosperity [PDF], would potentially establish a Palestinian state but give Israel sovereignty over an essentially undivided Jerusalem, including the Old City and the holy sites, relegating the Palestinian capital to a sliver of East Jerusalem. The plan would not grant Palestinian refugees the right to return to their former lands but promises some $50 billion worth of investment in a developing Palestinian state. The conceptual map provided in Trump’s plan suggests that the Palestinian territory in the West Bank would shrink to 70 percent as Israel annexes the Jordan Valley and all its settlements there. Critics have called the plan—which was created without consulting Palestinian leaders—a win for Israel on all the major final status issues. Palestinian Authority (PA) President Mahmoud Abbas rejected the plan, saying it “annuls the legitimacy of the Palestinian rights, our rights to self-determination, freedom, and independence, in our own state,” and asked the UN Security Council to follow suit, as the African Union, Arab League, and Organization of Islamic Cooperation have done. In June 2020, the PA made a counterproposal to establish a demilitarized, independent Palestinian state in Gaza, East Jerusalem, and the West Bank.
Despite its long-standing support for a two-state solution, the United States has traditionally not supported Palestinian bids for statehood at the United Nations, saying this matter should only be decided through negotiations with Israel. The PA has pursued full membership for Palestine at the United Nations since 2011, a move that requires approval by the Security Council, where the United States has a veto. The PA has yet to garner enough support for the bid, but in 2012, 138 countries at the UN General Assembly voted to recognize Palestine as a nonmember observer state.
What is the U.S. position on Jerusalem?
When the UN General Assembly voted to divide British-controlled Palestine into separate Arab and Jewish states in 1947, it set aside the city of Jerusalem as a corpus separatum, or separate body, recognizing its shared religious significance for Christians, Jews, and Muslims. However, newly independent Israel established its seat of government in the western half of the city and later captured East Jerusalem from Jordan in 1967. Israel then expanded the municipal borders of Jerusalem to incorporate neighboring Palestinian towns and effectively annexed it.
As part of the 1993 Oslo Accords—the last significant agreement on the dispute—Israel and the PLO affirmed that claims to Jerusalem would only be decided in final status negotiations. Today, Israel views all of Jerusalem as its capital, while the PA claims East Jerusalem as the seat of a future Palestinian state, viewing Israel’s hold on the land as an occupation.
For decades, the United States and most other countries that have relations with Israel kept their embassies in Tel Aviv, so as not to preempt a future peace deal. Although a 1995 U.S. law [PDF] required the relocation of the American embassy to Jerusalem, successive presidents waived the requirement “to protect the national security interests of the United States.” However, Trump declined to do so in 2017, and announced his intention to move the embassy to Jerusalem and recognize the city as Israel’s capital. Supporters of the relocation argued there was no national security imperative prohibiting the move, and that U.S. diplomatic representation to Israel ought to be based at the country’s seat of government. The announcement prompted Palestinian officials to break off relations with the Trump administration.
What is the U.S. position on Israeli settlements?
Shortly after the 1967 war, Israel began building settlements in some of the territories it had seized. Settlement construction began under Labor party governments seeking to strengthen defense in parts of the West Bank that had seen heavy fighting during the Arab-Israeli wars, but it increased rapidly as some settlers viewed the land as their religious and historical right, and others found economic incentives to live there. By 2019, some six hundred thousand Israelis were living in settlements in the West Bank and East Jerusalem.
For years, the United States officially condemned these settlements—branding them an obstacle to peace—but avoided outright calling them illegal to avoid the possibility that Israel would face international sanctions. A 1978 State Department legal opinion stated that Jewish settlements in occupied territory are not admissible under international law, yet President Ronald Reagan stated in a 1981 interview that the settlements were “ill-advised” but “not illegal.” George H.W. Bush was the first president to link the amount of aid that Israel would receive to its settlement building, deducting the cost of settlement construction from U.S. loan guarantees. However, Clinton later allowed exemptions for settlement construction in East Jerusalem and for “natural growth.” In 2004, George W. Bush wrote a letter to Israeli Prime Minister Ariel Sharon recognizing that the “new realities,” or settlements, would make it impossible for Israel to revert to pre-1967 borders in any peace agreement. Most administrations came to believe that Israel would keep its three largest settlement blocs in exchange for ceding other land to the Palestinians in any peace deal, thinking it unrealistic that Israel could force so many of its citizens to leave the settlements. While the Obama administration took actions to shield Israel from political movements that sought to penalize Israeli businesses operating in the West Bank, it also delivered a rebuke of Israel’s settlements by abstaining from a UN Security Council vote declaring the settlements illegal.
As it has done with other components of the Israeli-Palestinian conflict, the Trump administration has pivoted toward a view of Jewish settlements that is markedly pro-Israel. In November 2019, U.S. Secretary of State Mike Pompeo voiced disagreement with the 1978 State Department opinion, saying civilian settlements in the West Bank are “not, per se, inconsistent with international law,” and not an obstacle to the peace process. The announcement prompted more than one hundred members of Congress to sign a letter of disapproval [PDF]. Commenting on the move, CFR’s Gordon wrote that “if there was already a yellow light from the United States for settlement expansion, the [Trump] administration just turned it green.”
Under Trump’s peace plan, Israel would absorb about 30 percent of the West Bank by extending sovereignty to all Jewish settlements there and to the Jordan Valley. The plan has the general support of Prime Minister Benjamin Netanyahu and his former rival Benny Gantz, with whom he formed a unity government in April 2020. Netanyahu was expected to move forward with annexation in July 2020, a proposal condemned by U.S. lawmakers from both major parties, human rights experts, and leaders worldwide. However, as part of the Abraham Accord with the UAE, Israel agreed to halt annexation temporarily.
How much U.S. aid goes to Israelis and Palestinians?
The United States has long been Israel’s ally and its leading security collaborator because the United States supports the existence of a Jewish state. During the Cold War, many U.S. defense strategists saw Israel as the best partner in the fight against Soviet influence in the Middle East, and it later proved to be a strong contributor to U.S. counterterrorism efforts.
Today, Israel remains the United States’ closest strategic partner in the Middle East. Both countries are concerned about Iran’s nuclear ambitions and its support for Islamist militants, particularly Lebanon’s Hezbollah and Hamas, the Palestinian group that controls Gaza. As a result of these shared interests, the United States has pledged to help safeguard Israel’s military superiority over any hostile combination of countries in the region. By law, the U.S. government must ensure that any arms sales to other Middle Eastern states do not “adversely affect Israel’s qualitative military edge over military threats to Israel” [PDF].
The United States began providing Israel with military assistance after its withdrawal from Arab territories as part of the peace process. Washington considered it a responsibility to provide this security aid because Israel was taking risks for peace. The United States also gave large aid packages to Egypt and Jordan in exchange for their commitments to the peace process.
Since the end of World War II, the United States has provided more cumulative foreign aid to Israel than it has to any other country. The United States gave Israel significant economic assistance from 1971 to 2007, but due to Israel’s considerable economic growth beginning in the 1990s, it now receives mostly military aid. In fiscal year 2020, more than half of all U.S. foreign military aid [PDF] was headed to Israel, which uses most of it to purchase U.S. arms. Under a 2016 memorandum of understanding, the United States is committed to providing nearly $4 billion to Israel each year, including $500 million for missile defense.
For many years, the United States also provided aid to Palestinians, mostly to support government and humanitarian programs. Washington gave more than $5 billion total between 1994 and 2018. The United States has also provided more than $6 billion in aid to the UN Palestinian refugee agency (UNRWA) since 1950. Aid flows were restructured in 2007, after Hamas broke violently with the PA—led by the rival Fatah party—and seized control of the Gaza Strip. The United States considers Hamas a terrorist organization and takes measures to prohibit it from receiving any assistance.
U.S. aid to the Palestinians began shrinking under the Trump administration in 2018, as it reduced assistance to the West Bank and Gaza and discontinued contributions to UNRWA. In 2019, Trump signed an antiterrorism law that allowed Americans to sue recipients of U.S. foreign aid, including the PA, over alleged complicity in acts of war. Fearing lawsuits, the PA requested that Washington cut off its aid. Since then, Washington has only provided the Palestinians with a one-time donation of $5 million to combat the 2020 coronavirus pandemic.
What are the prospects for a resolution to the conflict?
The outlook for Israeli-Palestinian negotiations is bleak. It’s highly unlikely that the Palestinians will receive a package of concessions from Israel that is more favorable than those that the Palestinians have rejected in the past. Some experts have suggested that the prospects for a two-state solution will continue to fade, especially if the Israeli government annexes settlements in the West Bank and the Jordan Valley, actions it agreed to “suspend” as part of the Abraham Accord with the UAE. But many analysts say that deal and a similar one with Bahrain have reduced the likelihood of new talks between Israel and the PA. The two agreements run counter to the Arab Peace Initiative, which called for Israel to withdraw to pre-1967 borders and recognize an independent Palestinian state as conditions for Arab League member states to normalize relations with Israel. Meanwhile, political divisions between Hamas and the PA will remain a challenge to any future negotiated settlement.
These dynamics may put the Israelis and Palestinians on a path toward a one-state outcome, which many observers view as perilous given the possibility that, with Arabs forming at least half the population, Israel will no longer be a Jewish state. And if Israel were to deny Palestinians equal rights in order to remain a Jewish state, that would undermine its future as a democracy. Despite these concerns, there’s growing interest in the notion of a one-state solution. It has become more popular among Israelis [PDF], and a 2020 poll [PDF] of Palestinians showed that just over one-third would support it.
