"Trust Is Not A Birthright" -- War In Context

Tweet Mainly I like this article because it has a graphic representation of the strides Hamas had taken in stopping the rocket fire before Israel broke the truce in June. And the evidence comes Israel.

Look at this graph provided by the Israeli Foreign Ministry showing rocket attacks from Gaza per month during 2008. From January through June there were an average of 179 rocket attacks per month. From July through October there were an average of 3 rocket attacks per month.

For the residents of Sderot, those months were indeed a period of calm. But the calm ended when Israel unilaterally broke the ceasefire right after the US elections and just before Hamas and Fatah sat down for crucial reconciliation talks in Cairo.

If Israel, as it would currently have the world believe, was so strongly in favor of extending the six-month ceasefire, why did it attach so little value to what had already been accomplished? Why did it not acknowledge the effectiveness with which Hamas was holding up its side of the bargain? Why did it not demonstrate that it valued the calm by lifting or at least easing the economic embargo on Gaza in a significant way?
