A cynical joke in Israel defines ceasefire as the Israelis cease, the Arabs continue to fire. 
Except it isn't a joke.

A month and a half after Israel ended its campaign to stop rockets launched by Arabs in Gaza destroying Israel's southern territory and killing and injuring Israeli citizens

In an official protest to the United Nations, the Israel's Ambassador Gabriela Shalev noted that "there have been nearly 100 rocket and mortar attacks from the Gaza Strip" since the ceasefire on January 18, or over two per day. These have been increasing in number, with 12 rockets were fired at Sderot on March 1 alone.

Was I the only one rubbing my eyes in disbelief yesterday, as the Egyptian government hosted an "International Conference in Support of the Palestinian Economy for the Reconstruction of Gaza"? (snip)
 
I wonder if those eminentoes and worthies really believe that warfare in Gaza is a thing of the past, and that the time for reconstruction is nigh?

 in Sharm El-Sheikh, attended by delegations from 71 states, plus 16 regional, international, and financial organizations. Its stated goal was to raise US$2.8 billion, of which $1.3 was for rebuilding what had been destroyed in the course of Israel's recent war on Hamas (the rest would be sent to the Palestinian Authority to help improve its standing). The actual amount raised at the conference was $4.5 billion which, when added to previously committed funds, means the grant total for Gaza and the PA comes to $5.2 billion, to be disbursed over a two-year period. A delighted Egyptian foreign minister called the amount "beyond our expectations." U.S. Secretary of State Hillary Clinton called it "a very productive conference"

My best guess: this permits them subtly to signal Jerusalem that it better not attack Gaza again, because doing so will confront it with a lot of very angry donor governments – including, of course, the Obama administration.
Adding to the surreal quality is a blithe disregard for Israel's security needs. Consider the attitude of Douglas Alexander, international development secretary for Britain's Labour government, who pledged £30 million of his taxpayers' funds to rebuild houses, schools, and hospitals in Gaza. "There is a desperate need for tough restrictions on the supply of goods to be relaxed," he said, demanding next that "Israel must do the right thing and allow much-needed goods to get through to those men, women and children who continue to suffer."

That's very humanitarian of Mr. Alexander, but he willfully ignored Israeli expectations that Hamas will confiscate steel, concrete, and other imported construction materials to build more tunnels, bunkers, and rockets. After all, Hamas appropriated prior deliveries intended for civilians, and so blatantly that even the usually docile United Nations Relief and Works Agency protested.

Is this ignorance or mendacity? I suspect the latter; no one is that dumb.
