Looks like Israel has made a tiny drone that can carry a small shaped charge that can punch a hole is a gas tank or cylinder of flammable gas. With IR video and encrypted coms and larger plastic propellers that make a lot less noise they can fly in at 500 feet to an area and with no IR searchlight (dead reckoning via GPS or an Israeli secret GPS, waaay off band to our GPS) it can rreach an area, descend, light up, select target and self kill in contact with a target, or attach magnetically, set timer - OR - trigger remotely?
and fly the drone away. Drones with 30 minutes to do this, only 6 inches wide are on youtube. The era of small sabotage has begun. Expect Iran to also do this, and israel needs to operate a picket to stop these. I am sure Iran has assessed the fragments and will also make a picket...All informed spec about what I would do after that TED episode
