Looking at the destruction of Europe after WWII vs the destruction in Gaza City, it would not surprize me if the Palesimians were incapable of cleaning up and rebuilding the mess they brought upon themselves.
Europeans were able to rebuild, with some help. These guys, I doubt it.
Oh I don’t know, they are pretty good at building tunnels.
Just imagine if the same effort that they put into building tunnels was put into construction projects to improve the desert.
