The Israeli ministry of defence has become concerned about unmanned air vehicle export permits.
Whether UAS are becoming a weapon of choice for terror organisations was discussed here a few weeks ago. It was a natural result of the efforts by Hezbollah to penetrate Israeli airspace with a drone.
The UAS flew over the Mediterranean and when off the Gaza shore, it assumed an eastern flight path. After entering Israeli airspace it was shot down by an Israeli air force F-16.
Experts say that a terrorist attack is much more difficult with a UAS than with guns or bombs.
Iranian UAS have been launched into Israel in the past. After the Israeli air force shot down one in 2006, steps were taken to minimise the new threat.
Some sources say that the UAS used by Hezbollah took a "long twisted" route before arriving in the hands of the Lebanese terror organisation.
The foiled attempts were all primitive. But without doubt, the use of UAS for terror, whether for reconnaissance or attacks, will increase.
The terrorist, in most cases, does not need a high-end UAS. A basic platform with a GPS flight control system will do the job.
Israel has a vast job in defending the huge reservoirs of gas that was discovered off the Mediterranean shore.
A small UAS carrying a relatively limited amount of explosives could cause a disaster if it hit a production rig.
So Israel, one of the world's leading manufacturers of UAS, now faces a big problem. While many potential customers are negotiating the purchase of Israeli-made UAS, there are voices within the ministry of defence that are calling for a closer look at any proposed deal.
As always, every client signs an end-user obligation, but there are some indications that these were not always fulfilled.
