See Reigniting Violence, How Do Ceasefires End? by Nancy Kanwisher
79% of all conflict pauses were interrupted when Israel killed a Palestinian, while only 8% were interrupted by Palestinian attacks (the remaining 13% were interrupted by both sides on the same day).
“Thus, a systematic pattern does exist: it is overwhelmingly Israel, not Palestine, that kills first following a lull. Indeed, it is virtually always Israel that kills first after a lull lasting more than a week.
The lessons from these data are clear:
First, Hamas can indeed control the rockets, when it is in their interest. The data shows that ceasefires can work, reducing the violence to nearly zero for months at a time.
Second, if Israel wants to reduce rocket fire from Gaza, it should cherish and preserve the peace when it starts to break out, not be the first to kill.” http://www.huffingtonpost.com/nancy-kanwisher/reigniting-violence-how-d_b_155611.html

Also see The Truth About Cease-fire Violations Between Israel and Gaza by John Glaser
“Israel violates the cease-fires more often, bombs Gaza more times than Gaza rockets Israel, and kills more Palestinians than Palestinians kill Israelis. But these findings are not what is striking. What is striking about this is that almost everybody believes the opposite of the reality. Here’s Munayyer with more on that: …
Of the nearly 120 Israeli cease-fire violations during this period the New York Times reported on 17 of them. Additionally, most of these stories (eleven) came either during the first week of the cease-fire, when the issue was still fresh in readers’ minds, or since the escalation on December 20th. That means for the bulk of this period, during which Israel committed 87 cease-fire violations and causing some 91 Palestinian casualties over nearly a one year period there were only six stories on the topic. This represents a systematic failure to cover Israeli cease-fire violations.
Making matters worse is the way events are covered in the rare instances they are covered. In most cases, Israeli actions are described as a response to Palestinian actions. So while most Israeli cease-fire violations are not covered at all, those that are are explained as justified retaliation. Thus the reader is completely misled about the dynamics of fire, why the cease-fire is threatened and exactly what is going on in and around Gaza.” http://antiwar.com/blog/2014/02/06/the-truth-about-cease-fire-violations-between-israel-and-gaza/
