I think the current government  of Israel does not really want a ceasefire in Gaza at this time. Israel will not permit a ceasefire in Gaza until they have either taken it over or have made it like Hiroshima or both.

I also think that Israel was to a degree complicit in the vicious Hamas attack. They knew it was coming, took no steps to prevent it, and have used it as a respectable casus belli. So Israel is enlarging its borders, and expelling the unwelcome, in two ways: in the Westbank by infiltration and colonization, in Gaza by invasion.

So I anticipate that Israel will continue to raise objections to a ceasefire until it is satisfied that it owns Gaza.
