(According to the photo's EXIF information, that last picture may have been taken in 2009, and Islamic Jihad wanted to make the parade look more impressive.)
In an interview with Islamic Jihad media, the leader of the movement, Sheikh Ibrahim al-Najjar, "Abu Hazim," bragged that Islamic Jihad has not budged one iota from its founding principles of destroying Israel and replacing it with an Islamist state.
Najjar said that this year's anniversary festival was a "referendum of resistance," meaning that it is proof that Palestinian Arabs still embrace terror as their means of destroying Israel.
He also bragged:
Praise be to God, the al-Quds Brigades of military force [of Islamic Jihad] is powerful enough to dictate its will to invalidate any agreement that does not do justice to the Palestinians and did not give them them the right to return to their entire land.
People who still cling to the idea of the sacred "peace process" never really discuss Islamic Jihad and how it has effective veto power even in the unlikely event that Palestinian Arab leadership can accept a reasonable compromise with Israel.
In the wisdom of Oslo, it is better to leave all the impossible issues for the end of the "process."
