Egypt is acting like Israel. They want their border with Gaza to be secure, so they are doing something. They are creating a 500 meter buffer along the border to make it harder to smuggle weapons - both above ground and below it. This requires demolishing homes.
When Israel secures their borders the whole world, except the US, condemns them. How about Egypt? Is the UN preparing very strong words?
Also, the interests of Egypt and Israel certainly converge here.
