Show me where it says they need permission from Palestinians for those border agreements to be valid
They are Palestine's borders. Who else has the authority?
Again, show me where it says the Israels borders are not valid because of what you say.
I have read many articles discussing Israels borders with Egypt and Jordan. Not ONE of them suggest what you are saying. So surely you can show me some article that suggests what you are saying. In the mean time, I'll believe what I read on Wiki and other sites over what a rabid anti - Israeli says.
