Sinai panic creates terror
The rapid pace of the work at this time is eliminating the breaches in the old fence used to easily bring into Israel African migrants, as well as drugs and weapons for terrorists. As result of this, the huge sums earned by the northern Sinai Bedouins (to the tune of hundreds of thousands and possibly millions of dollars) have plummeted as of late.
It is no wonder then that Sinais Bedouins are panicking when they see their golden goose being slaughtered right before their eyes. They know that they cannot completely avert the construction of the fence, yet every delay in building it means an added profit of tens of thousands of dollars.
The modus operandi they are adopting at this time towards Israel is terror and deterrence, the same means used some months ago against Egyptian troops and security agents who attempted to block the smuggling routes to Israel. The Bedouins are not short on weapons; they possess huge depots of heavy machineguns, RPG rockets and launchers of all types, anti-tank and anti-aircraft missiles, as well as advanced Grad rockets and worse.
