In November 2012, the Israel Defense Forces launched Operation Pillar of Defense (Hebrew: , Amd Ann, literally: "Pillar of Cloud") which was an eight-day campaign in the Hamas-governed Gaza Strip, which began on 14 November 2012 with the killing of Ahmed Jabari, chief of the Gaza military wing of Hamas by an Israeli airstrike.The operation was preceded by a period with a number of mutual IsraeliPalestinian responsive attacks. According to the Israeli government, the operation began in response to the launch of over 100 rockets at Israel during a 24-hour period, an attack by Gaza militants on an Israeli military patrol jeep within Israeli borders, and an explosion caused by IEDs, which occurred near Israeli soldiers, on the Israeli side of a tunnel passing under the Israeli West Bank barrier. The Israeli government stated that the aims of the military operation were to halt rocket attacks against civilian targets originating from the Gaza Strip and to disrupt the capabilities of militant organizations. The Palestinians blamed the Israeli government for the upsurge in violence, accusing the IDF of attacks on Gazan civilians in the days leading up to the operation. They cited the blockade of the Gaza Strip and the occupation of West Bank, including East Jerusalem, as the reason for rocket attacks.During the course of the operation, the IDF claimed to have struck more than 1,500 sites in the Gaza Strip, including rocket launchpads, weapon depots, government facilities, and apartment blocks. According to a UNHCR report, 174 Palestinians were killed and hundreds were wounded. Many families were displaced. One airstrike killed ten members of the al-Dalu family. Some Palestinian casualties were caused by misfired Palestinian rockets landing inside the Gaza Strip. Eight Palestinians were executed by members of the Izz ad-Din al-Qassam Brigades for alleged collaboration with Israel.During the operation, Hamas, the al-Qassam Brigades and the Palestinian Islamic Jihad (PIJ) further intensified their rocket attacks on Israeli cities and towns, in an operation code named Operation Stones of Baked Clay (Arabic: , ijrat sijl) by the al-Qassam Brigades, firing over 1,456 rockets into Israel, and an additional 142 which fell inside Gaza itself. Palestinian militant groups used weapons including Iranian-made Fajr-5, Russian-made Grad rockets, Qassams, and mortars. Some of these weapons were fired into Rishon LeZion, Beersheba, Ashdod, Ashkelon, and other population centers. Tel Aviv was hit for the first time since the 1991 Gulf War, and rockets were fired at Jerusalem. The rockets killed three Israeli civilians in a direct hit on a home in Kiryat Malachi. By the end of the operation, six Israelis had been killed, two hundred forty were injured, and more than two hundred had been treated for anxiety by Magen David Adom. About 421 rockets were intercepted by Israel's Iron Dome missile defense system, another 142 fell on Gaza itself, 875 fell in open areas, and 58 hit urban areas in Israel. A bus in Tel Aviv was bombed by an Arab-Israeli, injuring 28 civilians.Canada, Germany, the United Kingdom, the United States, and other Western countries expressed support for what they considered Israel's right to defend itself, or condemned the Hamas rocket attacks on Israel. China, Iran, Russia, Egypt, Turkey, and several other Arab and Muslim countries condemned the Israeli operation. The United Nations Security Council held an emergency session on the situation, but did not reach a decision. After days of negotiations between Hamas and Israel, a ceasefire mediated by Egypt was announced on 21 November. Both sides claimed victory. Israel said that it had achieved its aim of crippling Hamas's rocket-launching ability, while Hamas stated that Israel's option of invading Gaza had ended. According to Human Rights Watch, both sides violated the laws of war during the fighting.

Israel (; Hebrew: יִשְׂרָאֵל, romanized: Yīsrāʾēl; Arabic: إِسْرَائِيل, romanized: ʾIsrāʾīl), officially the State of Israel (מְדִינַת יִשְׂרָאֵל, Medīnat Yīsrāʾēl; دَوْلَة إِسْرَائِيل, Dawlat ʾIsrāʾīl), is a country in Western Asia. It is situated on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea, and shares borders with Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest; it is also bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the economic and technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is unrecognized internationally.Israel has evidence of the earliest hominid migrations out of Africa. Canaanite tribes are archaeologically attested in the region since the Middle Bronze Age, while the kingdoms of Israel and Judah emerged during the Iron Age. The northern Kingdom of Israel was destroyed by the Neo-Assyrian Empire around 720 BCE, and the Kingdom of Judah was incorporated into the Neo-Babylonian Empire in 586 BCE. Some of the Judean population was exiled to Babylon, only to return after Cyrus the Great conquered the region. The Maccabean Revolt against Seleucid rule led to an independent Hasmonean kingdom by 110 BCE. The kingdom became a client state of the Roman Republic in 63 BCE, following which the Herodian dynasty was installed by 37 BCE, and in 6 CE, the former kingdom was finally incorporated into the Roman Empire as the province of Judaea (Latin: Iudaea). A series of unsuccessful Jewish revolts against the Romans that broke out during the first and second centuries resulted in the destruction of Jerusalem, the expulsion of many Jews, and the renaming of Iudaea to Syria Palaestina. In the 7th century CE, the Byzantine-ruled Levant was taken by Arab forces and incorporated into the Rashidun Caliphate. It remained in Muslim hands until the First Crusade of 1096–1099 re-established a Christian sovereign presence; Crusader control was partly dismantled by the Ayyubids in 1187, but ultimately lasted until 1291. The Mamluk Sultanate of Egypt extended its control over the region by the end of the 13th century until its defeat in 1516 to the Ottoman Empire. During the 19th century, a national awakening among Jews led to the founding of Zionism, a movement that espouses the return of a Jewish homeland in Palestine, also known as the Land of Israel, which was followed by the immigration of diaspora Jews.

Following World War I, Britain controlled the entirety of the territory of what makes up Israel, the Palestinian territories, and Jordan as a League of Nations mandate. After World War II, the newly formed United Nations adopted the Partition Plan for Palestine in 1947, recommending the creation of independent Arab and Jewish states, and an internationalized Jerusalem. The plan was accepted by the Jewish Agency but rejected by Arab leaders. Following a civil war within Mandatory Palestine between Yishuv and Palestinian Arab forces, Israel declared independence at the termination of the British Mandate. The war internationalized into the 1948 Arab–Israeli War between Israel and several surrounding Arab states and concluded with the 1949 Armistice Agreements that saw Israel in control of most of the former mandate territory, while the West Bank and Gaza were held by Jordan and Egypt respectively. Israel has since fought several wars with Arab countries, and since the Six-Day War in June 1967 has occupied several territories, and continues to occupy the Golan Heights and the Palestinian territories of the West Bank, including East Jerusalem, and the Gaza Strip, though whether Gaza remains occupied following the Israeli disengagement is disputed. Israel has effectively annexed East Jerusalem and the Golan Heights, though these actions have been rejected as illegal by the international community, and established settlements within the occupied territories, which the international community also considers illegal under international law. Efforts to resolve the Israeli–Palestinian conflict have not resulted in a final peace agreement, while Israel has signed peace treaties with both Egypt and Jordan, and more recently has normalized relations with a number of other Arab countries.

In its Basic Laws, Israel defines itself as a Jewish and democratic state, and as the nation-state of the Jewish people. The country is a liberal democracy with a parliamentary system, proportional representation, and universal suffrage. The prime minister serves as head of government and the Knesset is the unicameral legislature. Israel is a developed country and an OECD member, and has a population of over 9 million people as of 2021. It has the world's 31st-largest economy by nominal GDP, and is the most developed country that is currently in conflict. The standard of living in Israel is the highest in the Middle East, and the country ranks high on the global HDI list. Israel also ranks among the world's top countries by percentage of citizens with military training, percentage of citizens holding a tertiary education degree, research and development spending by GDP percentage, women's safety, life expectancy, innovativeness, and happiness.
