As much as one might see Abbas as a more moderate player, the Palestinians have through the decades proven themselves to be untrustworthy to the max.
Jordan, Lebanon, on the West Bank, and Gaza, with regard to Egypt, there’s simply no basis for anyone with half a clue over there to grant them any favors.
Personally, I think Egypt would be rather dumb to risk their border security to the PA.
These are people who like to wear bombs and detonate them. This is the sort of people they think can be peace partners?
Really?
Egypt will still be on their side of the border. The Palestinian Authority will be on the Gaza side ... :-) ...
Between “Hamas” or “The Palestinian Authority” on the Gaza side, Egypt wants the PA.
