In the postmortems of the terrorist car attacks in Jerusalem, it is easy to see the writing on the wall.
Ibrahim al-Akary, the terrorist who on Wednesday ran over crowds of people waiting to cross the street and catch the Jerusalem Light Rail, was the brother of one of the terrorist murderers freed in exchange for IDF hostage Gilad Schalit. He had placed the photograph on his Facebook page of Moataz Hejazi, the terrorist killed by police after shooting Yehuda Glick outside the Begin Heritage Center last Wednesday.
A few days before Abdur Rahman Slodi got into his car and mowed down three-month-old Chaya Zissel Braun and a dozen other pedestrians two weeks ago, PA Chairman Mahmoud Abbas exhorted the Palestinians to prevent Jews from visiting the Temple Mount, Judaism’s holiest site, by all means possible.
Slodi had served time in prison for terrorist offenses and was active on social media where he expressed murderous hatred for Jews and a desire to kill them.
So yes, the writing was on the wall. But unfortunately, the writing is on all the walls, or Facebook walls. It is not at all clear how Israeli security services could have known to distinguish these men from the thousands of other Palestinians and Jerusalem Arabs who hate Israel, support the murder of Jews and identify with various terrorist organizations.
On Thursday security forces arrested several people in villages around Hebron with suspected ties to Akary. So he may not have been acting on his own. But all the same, neither he nor Slodi seem to have been directed to carry out their attacks by a cell commander who himself was directed by a higher level terrorist operative. Rather, in all likelihood, something triggered both men to carry out attacks in a wholly independent or semi-independent manner.
The question is, what was the trigger and how was it pulled?
