This is a legacy of Israel's policy of dispossession that precedes the creation of Israel.
With Hamas having become stronger than ever, more defiant than ever, instead of docilely submitting to Israel, and with Israel's goal of eliminating all rocket manufacturing facilities and stockpiles of rockets in Gaza not having been accomplished, and with the truce eliminating any further attempts by Israel to strike Gaza again, the indications are, given Israel's history in this regard, that Israel will, as soon as it can, create another incident to provoke Hamas once more into retaliating and use that retaliation as an excuse, once more, to mount a better planned and more massive attack that will inflict massive destruction in a short time, before the world starts putting pressure on Israel once again to agree to a ceasefire.
The words of Israeli President in a recent CNN interview are ominous. He let it slip that "You don't negotiate with terrorists. You strike'" Perhaps even more ominous is what Israeli Prime Minister Netanyahu said: "I know there are citizens that expected a wider military operation and it could be that it will be needed. But at this time, the right thing for the state of Israel is to take this opportunity to reach a lasting cease fire." (emphasis added)
