The problem of having to use missiles costing hundreds of thousands of dollars to destroy targets that are cheap up to a thousand dollars has been felt by Israel for the first time in all its acuteness. It is forced to use Tamir missiles from the Iron Dome antiaircraft system to destroy cheap Palestinian Qassam missiles made in clandestine workshops. The cost of each is 150 thousand dollars. So the terrorists, firing 1,000 rockets, incur a cost of one million dollars, while Israel incurs a cost of 150 million dollars! These are not comparable costs. And, for example, the RIM116 Rolling Airframe Missile, which is on the world's most modern aircraft carrier "Gerald Ford" was already estimated in 2014 at 998,000 dollars. Now its price tag has probably passed the milliondollar mark. Now imagine a swarm of a hundred kamikaze drones attacking an aircraft carrier. How much would it cost the U.S. people to neutralize that attack? A billion dollars! And such a swarm, and even controlled by artificial intelligence this is no longer a fantasy, but a reality.
