The PA has withheld or drastically limited the passports for years. But in one of the agreements with Hamas for "unity," Mahmoud Abbas promised to rectify the situation, saying that a passport is "the inherent right of every Palestinian."
"Unity" has accomplished its main purpose: It stopped a possible revolt against Fatah and Hamas with false promises. And the two parties will continue to do whatever they can to maintain the status quo, and to save their own necks and positions of power.
The Palestinian Arab media is mostly aligned with one side or the other, so there are very few articles complaining that "unity" has been a sham. Instead there are articles blaming the others for the stalemate.
