“On some days, as many as 20 drones might fly across the Egyptian border into Israel from different points. It does not matter that much if Israel shoots some of them down or uses electronic warfare spectrum weapons to get others to crash or land in an open field to be seized. As long as a certain percentage of the cargo gets through, the smugglers can make millions.
THE SMUGGLERS also learned that they could send a vast amount of weapons across the border. Some of these weapons might be for Arab Israelis or Bedouin. Still, others might be eventually destined for Hamas or even for being transferred to terrorist groups in the Palestinian Authority-controlled portions of the West Bank.”
