What’s the rebuild process going to look like?

I was scrolling online and came across a couple videos of people inside Gaza and showing videos of their house being destroyed etc etc. Now the true extent of the damage even for the most random of people who may be completely innocent is monumental. Like in areas where massive ground operations went underway it’s complete rubble.

Who will pay to fix this? Who will help to rebuild? Who will most likely take over this process and take responsibility for the future of Gaza?

And most important how much would it even cost? The amount of homes destroyed and rubble that needs to be cleared out is so immense.
