Palestinian Fedayeen insurgency (1950s–1960s) – Palestinian attacks and reprisal operations carried out by the Israel Defense Forces during the 1950s and 1960s. These actions were in response to constant fedayeen incursions during which Arab guerrillas infiltrated from Syria, Egypt, and Jordan into Israel to carry out attacks against Israeli civilians and soldiers. The policy of the reprisal operations was exceptional due to Israel's declared aim of getting a high 'blood cost' among the enemy side which was believed to be necessary in order to deter them from committing future attacks.
Suez Crisis (October 1956) – A military attack on Egypt by Britain, France, and Israel, beginning on 29 October 1956, with the intention to occupy the Sinai Peninsula and to take over the Suez Canal. The attack followed Egypt's decision of 26 July 1956 to nationalize the Suez Canal after the withdrawal of an offer by Britain and the United States to fund the building of the Aswan Dam. Although the Israeli invasion of the Sinai was successful, the United States and USSR forced it to retreat. Even so, Israel managed to re-open the Straits of Tiran and pacified its southern border.
War of Attrition (1967–1970) – A limited war fought between the Israeli military and forces of the Egyptian Republic, the USSR, Jordan, Syria, and the Palestine Liberation Organization from 1967 to 1970. It was initiated by the Egyptians as a way of recapturing the Sinai from the Israelis, who had been in control of the territory since the mid-1967 Six-Day War. The hostilities ended with a ceasefire signed between the countries in 1970 with frontiers remaining in the same place as when the war began.
Yom Kippur War (October 1973) – Fought from 6 to 26 October 1973 by a coalition of Arab states led by Egypt and Syria against Israel as a way of recapturing part of the territories which they lost to the Israelis back in the Six-Day War. The war began with a surprise joint attack by Egypt and Syria on the Jewish holiday of Yom Kippur. Egypt and Syria crossed the cease-fire lines in the Sinai and Golan Heights, respectively. Eventually Arab forces were defeated by Israel and there were no significant territorial changes.
Palestinian insurgency in South Lebanon (1971–1982) – The PLO relocated to South Lebanon from Jordan, staged attacks on the Galilee, and used South Lebanon as a base for international operations. In 1978, Israel launches Operation Litani – the first Israeli large-scale invasion of Lebanon, which was carried out by the Israel Defense Forces in order to expel PLO forces from the territory. Continuing ground and rocket attacks, and Israeli retaliations, eventually escalate into the 1982 War.
1982 Lebanon War (1982) – Began on 6 June 1982, when the Israel Defense Forces invaded southern Lebanon to expel the PLO from the territory. The Government of Israel ordered the invasion as a response to the assassination attempt against Israel's ambassador to the United Kingdom, Shlomo Argov, by the Abu Nidal Organization and due to the constant terror attacks on northern Israel made by the Palestinian guerrilla organizations which resided in Lebanon. The war resulted in the expulsion of the PLO from Lebanon and created an Israeli Security Zone in southern Lebanon.
Second Intifada (2000–2005) – Second Palestinian uprising, a period of intensified violence, which began in late September 2000.
2006 Lebanon War (summer 2006) – Began as a military operation in response to the abduction of two Israeli reserve soldiers by the Hezbollah. The operation gradually strengthened, to become a wider confrontation. The principal participants were Hezbollah paramilitary forces and the Israeli military. The conflict started on 12 July 2006 and continued until a United Nations-brokered ceasefire went into effect on 14 August 2006, though it formally ended on 8 September 2006, when Israel lifted its naval blockade of Lebanon. The war resulted in a stalemate.
Gaza War or Operation Cast Lead (December 2008 – January 2009) – Three-week armed conflict between Israel and Hamas during the winter of 2008–2009. In an escalation of the ongoing Israeli–Palestinian conflict, Israel responded to ongoing rocket fire from the Gaza Strip with military force in an action titled "Operation Cast Lead". Israel opened the attack with a surprise air strike on 27 December 2008. Israel's stated aim was to stop such rocket fire from and the import of arms into Gaza. Israeli forces attacked military and civilian targets, police stations, and government buildings in the opening assault. Israel declared an end to the conflict on 18 January and completed its withdrawal on 21 January 2009.
2021 Israel–Palestine crisis or Operation Guardian of the Walls (May 2021) – Riots between Jews and Arabs in Israeli cities. Hamas fired rockets into Israel, with Iron Dome intercepting the most dangerous projectiles. Israel began airstrikes in Gaza.

In time, however, Arafat and his guerrilla leadership decided that they would have to withdraw, leaving no military and very little political or symbolic presence behind. Their enemy's firepower and overall strategic advantage were too great and it was apparently ready to use them to destroy the whole city over the heads of its inhabitants. The rank and file did not like this decision, and there were murmurings of 'treason' from some of Arafat's harsher critics. Had they not already held out, far longer than any Arab country in any former war, against all that the most powerful army in the Middle East – and the fourth most powerful in the world, according to Sharon – could throw against them? (...) But [Palestinians] knew that, if they expected too much, they could easily lose [Lebanese Muslim support] again. 'If this had been Jerusalem', they said, 'we would have stayed to the end. But Beirut is not outs to destroy.
