Arab-Israeli wars

After decades of confrontations between Arabs and Jews under the British mandate of Palestine, where both communities sought self-determination after the fall of the Ottoman Empire in 1922, the United Kingdom announced its intention in 1947 to withdraw its forces from Palestine and endorsed United Nations Resolution 181, which partitioned the British mandate into a Jewish state and an Arab state. The plan, although accepted by the international community, was rejected by the Arabs, and in May 1948, as British forces withdrew, Israel was born in a region with unresolved disputes over borders, security, land ownership, and other matters. Since that time, Israel has fought a number of conflicts with various Arab forces, most notably in 1948–49, 1956, 1967, 1973, 1982, 2006, and 2023–present. This article focuses on those conflicts with significant consequences for the broader Middle East region.

1948–49: Israel’s War of Independence and the Palestinian Nakba

On November 29, 1947, the United Nations (UN) voted to partition the British mandate of Palestine into a Jewish state and an Arab state (see United Nations Resolution 181). Clashes broke out almost immediately between Jews and Arabs in Palestine, beginning with the Arab ambush of a bus carrying Jewish passengers from Netanya to Jerusalem on November 30. As British troops prepared to withdraw from Palestine, conflict continued to escalate, with both Jewish and Arab forces committing hostile acts. Among the most infamous events was the attack on the Arab village of Deir Yassin on April 9, 1948. The news of a massacre there by Irgun Zvai Leumi and the Stern Gang forces spread widely and inspired both panic and retaliation. Days later, Arab forces attacked a Jewish convoy headed for Hadassah Hospital, killing 78.

On the eve of the British forces’ May 15, 1948, withdrawal, Israel declared independence. The fighting intensified immediately: Egypt launched an aerial assault on Tel Aviv, and, the next day, Arab forces from Egypt, Transjordan (Jordan), Iraq, Syria, and Lebanon occupied the areas in southern and eastern Palestine not apportioned to the Jews by the UN partition of Palestine and then captured East Jerusalem, including the small Jewish quarter of the Old City. The Israelis, meanwhile, won control of the main road to Jerusalem through the Yehuda Mountains (“Hills of Judaea”) and successfully repulsed repeated Arab attacks. By early 1949 the Israelis had managed to occupy all of the Negev up to the former Egypt-Palestine frontier, except for the Gaza Strip.

Between February and July 1949, as a result of separate armistice agreements between Israel and each of the Arab states, a temporary frontier was fixed between Israel and its neighbors. In Israel, the war is remembered as its War of Independence. In the Arab world, it came to be known as the Nakba (“Catastrophe”) because of the large number of refugees and displaced persons resulting from the war.

1956: Suez Crisis

Tensions mounted again with the rise to power of Egyptian Pres. Gamal Abdel Nasser, a staunch Pan-Arab nationalist. Nasser took a hostile stance toward Israel. In 1956 Nasser nationalized the Suez Canal, a vital waterway connecting Europe and Asia that was largely owned by French and British concerns. France and Britain responded by striking a deal with Israel—whose ships were barred from using the canal and whose southern port of Eilat had been blockaded by Egypt—wherein Israel would invade Egypt; France and Britain would then intervene, ostensibly as peacemakers, and take control of the canal.

In October 1956 Israel invaded Egypt’s Sinai Peninsula. In five days the Israel Defense Forces (IDF) captured Gaza, Rafah, and Al-ʿArīsh—taking thousands of prisoners—and occupied most of the peninsula east of the Suez Canal. The Israelis were then in a position to open sea communications through the Gulf of Aqaba. In December, after the joint Anglo-French intervention, a UN Emergency Force was stationed in the area, and Israeli forces withdrew in March 1957. Though Egyptian forces had been defeated on all fronts, the Suez Crisis, as it is sometimes known, was seen by Arabs as an Egyptian victory. Egypt dropped the blockade of Eilat. A UN buffer force was placed in the Sinai Peninsula.

1967: Six-Day War

Arab and Israeli forces clashed for the third time June 5–10, 1967, in what came to be called the Six-Day War (or June War). In early 1967 Syria intensified its bombardment of Israeli villages from positions in the Golan Heights. When the Israeli Air Force shot down six Syrian MiG fighter jets in reprisal, Nasser mobilized his forces near the Sinai border, dismissing the UN force there, and he again sought to blockade Eilat. In May 1967 Egypt signed a mutual defense pact with Jordan.

Israel answered this apparent Arab rush to war by staging a sudden air assault, destroying Egypt’s air force on the ground. The Israeli victory on the ground was also overwhelming. Israeli units drove back Syrian forces from the Golan Heights, took control of the Gaza Strip and the Sinai Peninsula from Egypt, and drove Jordanian forces from the West Bank. Importantly, the Israelis were left in sole control of Jerusalem.

1973: Yom Kippur War

The sporadic fighting that followed the Six-Day War again developed into full-scale war in 1973. On October 6, the Jewish holy day of Yom Kippur (thus, “Yom Kippur War”), Israel was caught off guard by Egyptian forces crossing the Suez Canal and by Syrian forces crossing into the Golan Heights. The Arab armies showed greater aggressiveness and fighting ability than in the previous wars, and the Israeli forces suffered heavy casualties. The Israeli army, however, reversed many of its early losses and pushed its way into Syrian territory and encircled the Egyptian Third Army by crossing the Suez Canal and establishing forces on its west bank. Still, it never regained the seemingly impenetrable fortifications along the Suez Canal that Egypt had destroyed in its initial successes.

The fighting, which lasted through the Islamic holy month of Ramadan, came to an end on October 26. Israel signed a formal cease-fire agreement with Egypt on November 11 and with Syria on May 31, 1974. A disengagement agreement between Israel and Egypt, signed on January 18, 1974, provided for Israeli withdrawal into the Sinai west of the Mitla and Gidi passes, while Egypt was to reduce the size of its forces on the east bank of the canal. A UN peacekeeping force was established between the two armies. This agreement was supplemented by another, signed on September 4, 1975.

On March 26, 1979, Israel and Egypt signed a peace treaty formally ending the state of war that had existed between the two countries for 30 years. Under the terms of the treaty, which had resulted from the Camp David Accords signed in 1978, Israel returned the entire Sinai Peninsula to Egypt, and, in return, Egypt recognized Israel’s right to exist. The two countries subsequently established normal diplomatic relations.

1982: Lebanon War

On June 5, 1982, less than six weeks after Israel’s complete withdrawal from the Sinai, increased tensions between Israelis and Palestinians resulted in the Israeli bombing of Beirut and southern Lebanon, where the Palestine Liberation Organization (PLO) had a number of strongholds. The following day Israel invaded Lebanon, and by June 14 its land forces reached as far as the outskirts of Beirut, which was encircled, but the Israeli government agreed to halt its advance and begin negotiations with the PLO. After much delay and massive Israeli shelling of west Beirut, the PLO evacuated the city under the supervision of a multinational force. Eventually, Israeli troops withdrew from west Beirut, and the Israeli army had withdrawn from areas north of the Līṭāni River by June 1985. Hezbollah, a militant group that formed as a militia to resist the Israeli invasion in 1982, continued to engage in a guerrilla campaign against Israeli forces until they withdrew fully in May 2000.

2006: Second Lebanon War

After Israel’s withdrawal from Lebanon, Hezbollah continued to press Israel over border disputes and Israel’s detention of Lebanese prisoners. On July 12, 2006, Hezbollah launched a barrage of rockets into northern Israel, diverting the IDF’s attention as Hezbollah fighters infiltrated the border, killing several Israeli soldiers and capturing two others in an attempt to pressure Israel into releasing Lebanese prisoners. Israel launched an offensive into southern Lebanon to recover the captured soldiers, beginning with an extensive air campaign that targeted infrastructure as far north as Beirut and later a ground offensive that aimed to push Hezbollah away from the Israeli-Lebanese border. Several Arab leaders criticized Hezbollah for inciting the conflict, which left more than one thousand Lebanese dead and about one million others displaced. Nevertheless, Hezbollah’s ability to fight the IDF to a standstill won it praise throughout much of the Arab world. When hostilities came to an end on August 14, Israeli leaders claimed that they had met most of the war’s objectives, but the abducted soldiers remained in Hezbollah’s custody (their remains were later exchanged through UN-brokered negotiations in 2008) and the handling of the war was heavily scrutinized by the Israeli public.

2023–present: Israel-Hamas War

Throughout the 20th century and the first years of the 21st century the major conflicts between Israeli forces and Arab forces were either driven by non-Palestinian actors or took place on foreign soil. After Hamas, a militant Palestinian movement, took control of the Gaza Strip in 2007, the enclave came under blockade by Israel and Egypt and a number of armed conflicts between Israel and Hamas took place in the territory, most notably in 2008, 2012, 2014, and 2021. The consequences of those conflicts largely remained contained within the enclave.

On October 7, 2023, Hamas led the most brutal assault against Israel since its independence, killing some 1,200 people and taking more than 240 others hostage. The attack, which caught Israeli forces off guard on the solemn Jewish holiday of Shemini Atzeret, occurred under the shadow of the 50th anniversary of the Yom Kippur War. With thousands of rockets launched into Israel in the span of 20 minutes, thus distracting the IDF while Hamas militants infiltrated the border and captured both civilians and soldiers, the assault echoed—and amplified—that of Hezbollah in the Lebanon War in 2006. Netanyahu vowed to dismantle and destroy Hamas using “all the power” of the IDF, and the next day Israel declared a state of war.

In the weeks that followed, the IDF’s air strikes in the crowded enclave were devastating. By the end of October, when Israel launched its ground invasion, more than half of the Gaza Strip’s population had been displaced, and the war had become the deadliest for Palestinians since the war of 1948. Despite efforts by Qatar and Egypt to mediate the return of the hostages and the cessation of violence—with short-lived success in late November—the war leveled much of the Gaza Strip and led to a calamitous humanitarian crisis. Moreover, the conflict inspired an escalation in conflict with allies of Hamas, including Hezbollah, which stepped up a series of confrontations with Israel that had begun before October 7, and the Houthi movement, which disrupted global shipping by attacking ships in the Red Sea. At the end of the year Israel faced tremendous international pressure to ease its offensive, and in February a rift emerged between Israel and the United States, Israel’s most important source of international support. Meanwhile, efforts to reach a cease-fire between Israel and Hamas continued, although Hamas refused to accept any proposal that did not guarantee a permanent end to hostilities and the full withdrawal of Israeli forces.
