Bombings for a couple weeks, escalate the humanitarian situation, have Egypt come in saying oh we’ll take care of the refugees. But make them look reluctant about it. Even though they’re getting some compensation on the other side. Then open the border while continuing the bombing. To get as many civilians to run out of the territory as quickly as possible.

That's literally what former IDF general Giora Eiland is calling for in his op-ed: https://www.ynetnews.com/article/sju3uabba

Israel issued a stern warning to Egypt and made it clear that it would not permit humanitarian aid from Egypt to enter Gaza. Israel needs to create a humanitarian crisis in Gaza, compelling tens of thousands or even hundreds of thousands to seek refuge in Egypt or the Gulf.

And the conditions he wants to create are enough that one might consider them genocidal: https://en.wikipedia.org/wiki/Genocide_Convention

Egypt is reluctant because Palestinians refugees have caused trouble before in their country, the economy isn’t doing well and they have high unemployment at the moment—that’s three good reasons to be reluctant that make sense.
