In this context Eqypt would be Egyptian Government.
Arab Powers would be current Arab State Governments.

No doubt there are millions of Arab who are genuinely concerned about the plight of Palestinians.
The current ruling class wants to keep the status quo. Palestinians remaining in lifetime cycle of violence is part of that status quo.

Ironically the 1979 treaty does have stipulations about the Gaza-Eqypt border. It requires Egypt to control it's border to prevent flow of smuggling, weapons, and extremist. Over the last 3 decades the ONLY thing flowing through the Egypt-Gaza border has been smuggling (souce of income for Hamas), weapons and extremist.

Nothing in 1979 treaty prevents Egypt from conducting legitimate trade, or allowing high education visas, building water or electricity links.

It is a CHOICE. Egypt (once again the government) has chosen to keep Palestinians is a state of suffering and to empower Hamas and other radicals because it achieves goals of Egyptian government.
