Looking for more info on the matter, do you have sources? Also, do you have a specific contention with the article? It would be more constructive if you could do more than claim it is a lie and that Sisi supports Israel.
Sisi immediately closed the Rafa border crossing within 24 hours of his coup. He undid Morsi’s policy and went against popular Egyptian public opinion by keeping the land and sea blockade of Gaza in force. While Morsi called for renegotiation of the Israel-Egypt peace treaty, Sisi shut that talk down and went back to the old Mubarak policies. It’s like asking me to cite that the border has been closed for the last 10 years.
I’m just quibbling with the Egyptian government’s statement that they’re working in Palestinians’ interests or for peace when they clearly aren’t. Egyptian military is firmly and openly anti-Hamas and views them as part of the MB, which is why they have helped Israel against them. It’s been widely reported that Sisi even took bribes from Saudi and UAE to maintain the actions against Palestinians.
It is probably true that Egyptian government does not care very much for the Palestinian's interests. That being said, if there is a shift on their part to promote a united front in Palestine, this should be favorable to the Palestinian people; even if not done so for their sake but as a part of geopolitical shifts. Such can be seen in the regional shift away from the USA, as can be seen in the case of Saudi Arabia.
