Interesting article from 2012. with past ceasefires and truces violated by israel A small portion:
2012 - On November 14, two days after Palestinian factions in Gaza agree to a truce following several days of violence, Israel assassinates the leader of Hamas’ military wing, Ahmed Jabari, threatening to escalate the violence once again after a week in which at least six Palestinian civilians are killed and dozens more wounded in Israeli attacks.
2012 - On March 9, Israel violates an Egyptian-brokered ceasefire and assassinates the head of the Gaza-based Popular Resistance Committees, sparking another round of violence in which at least two dozen Palestinians are killed, including at least four civilians, and scores more wounded. As usual, Israel claims it is acting in self-defense, against an imminent attack being planned by the PRC, while providing no evidence to substantiate the allegation. Following the assassination, Israeli journalist Zvi Bar’el writes in the Haaretz newspaper:
"It is hard to understand what basis there is for the assertion that Israel is not striving to escalate the situation. One could assume that an armed response by the Popular Resistance Committees or Islamic Jihad to Israel’s targeted assassination was taken into account. But did anyone weigh the possibility that the violent reaction could lead to a greater number of Israeli casualties than any terrorist attack that Zuhair al-Qaisi, the secretary-general of the Popular Resistance Committees, could have carried out? “In the absence of a clear answer to that question, one may assume that those who decided to assassinate al-Qaisi once again relied on the ‘measured response’ strategy, in which an Israeli strike draws a reaction, which draws an Israeli counter-reaction.”
Just over two months prior, on the third anniversary of Operation Cast Lead, Israeli army Chief of Staff Lt. Gen. Benny Gantz tells Israel’s Army Radio that Israel will need to attack Gaza again soon to restore its power of “deterrence,” and that the assault must be “swift and painful,” concluding, “We will act when the conditions are right.”
2011 - On October 29, Israel breaks a truce that has maintained calm for two months, killing five Islamic Jihad members in Gaza, including a senior commander. The following day, Egypt brokers another truce that Israel proceeds to immediately violate, killing another four IJ members. In the violence, a total of nine Palestinians and one Israeli are killed.
2008 - In November, Israel violates a ceasefire with Hamas and other Gaza-based militant groups that has been in place since June, launching an operation that kills six Hamas members. Militant groups respond by launching rockets into southern Israel, which Israel shortly thereafter uses to justify Operation Cast Lead, its devastating military assault on Gaza beginning on December 27. Over the next three weeks, the Israeli military kills approximately 1400 Palestinians, most of them civilians, including more than 300 children. A UN Human Rights Council Fact Finding Mission led by South African jurist Richard Goldstone subsequently concludes that both Israel and Hamas had committed war crimes and crimes against humanity during the fighting, a judgment shared by human rights organizations such as Amnesty International and Human Rights Watch.
2002 - On July 23, hours before a widely reported ceasefire declared by Hamas and other Palestinian groups is scheduled to come into effect, Israel bombs an apartment building in the middle of the night in the densely populated Gaza Strip in order to assassinate Hamas leader Salah Shehada. Fourteen civilians, including nine children, are also killed in the attack, and 50 others wounded, leading to a scuttling of the ceasefire and a continuation of violence.
2002 - On January 14, Israel assassinates Raed Karmi, a militant leader in the Fatah party, following a ceasefire agreed to by all Palestinian militant groups the previous month, leading to its cancellation. Later in January, the first suicide bombing by the Fatah linked Al-Aqsa Martyr’s Brigade takes place.
2001 - On November 23, Israel assassinates senior Hamas militant, Mahmoud Abu Hanoud. At the time, Hamas was adhering to an agreement made with PLO head Yasser Arafat not to attack targets inside of Israel. Following the killing, respected Israeli military correspondent of the right-leaning Yediot Ahronot newspaper, Alex Fishman, writes in a front-page story: “We again find ourselves preparing with dread for a new mass terrorist attack within the Green Line [Israel’s pre-1967 border]… Whoever gave a green light to this act of liquidation knew full well that he is thereby shattering in one blow the gentleman’s agreement between Hamas and the Palestinian Authority; under that agreement, Hamas was to avoid in the near future suicide bombings inside the Green Line…” A week later, Hamas responds with bombings in Jerusalem and Haifa.
2001 - On July 25, as Israeli and Palestinian Authority security officials meet to shore up a six-week-old ceasefire, Israel assassinates a senior Hamas member in Nablus. Nine days later, Hamas responds with a suicide bombing in a Jerusalem pizzeria.
