The Palestinians can not fight Israel militarily. The Palestinians just want to make a point, namely that they were forcibly expelled from their homes and villages by the Jews 70 years ago.
Indeed, if Jews had the right to commemorate events dating back 3000 years ago, the Palestinians have the right to remember their Nakba.
They follow a pattern although there's never a 'lead bird' that represents either Hamas or the PA. Doesn't matter these coo coo birds know the well worn road to their own destruction. Maybe they can one day find their way home to the Arab/Muslim homelands?
a few aircraft filled with porcine slaughterhouse refuse dropped on the heads of the gaza sand rats, and party over with no casualties. Muhammed may need a bath, though.
The size of the march will depend on whether Gazans fear Hamas more than Israel, anyway noone believes they can forcibly cross the border, when some Gazans turn around to go back, then fights will start between the marchers and IDF does not need do anything.
