Sorry, for the simplicity of what I'm saying. I'm new to this and trying to learn. 
From what I've seen, many Palestinians in Gaza are being moved to camps elsewhere. Sadly, many have been killed too.
The photos of the area suggest that much of Gaza is ruined and will need to be re-built.
If hypothetically all Palestinians were moved elsewhere, would Israel then be able to "claim" Gaza? Would the UN etc be allowed to stop them? Would the West Bank be able to claim it?
Any insight appreciated?
