Unfortunately I don't see it as very likely that Israel will give back all the territory in Gaza and provide aid to the Palestinians to rebuild.
Gaza was quite beautiful! And given its prime location on the mediterranean sea, I don't see why it couldn't be built up again.

But of course the massive mistake was not eradicating the evil terrorist genocidal mentality of its nominal leadership, Hamas. Israel (and the world) shouldn't make that mistake again.
Gazan Palestinians don't even have limited local rule the way Chinese autonomous regions or Puerto Rico do.
Note that despite aid and the occupation, Japan had significant unrest following the war. The Communist Party of Japan's candidate Inejirou Asanuma was assassinated by an imperial revanchist on Oct 12, 1960 [1].
