Cram is much safer than a SA flying up and hitting something. But even then it’s rarer someone gets hit by a iron dome rocket. How many have been fired in Gaza War? 10,000? 20,000? How many injuries? Less than 10?
Laser, it is the future. The cost per shot is Pennies on the dollar. Laser is perfect for small drones, one blast and it’s out of the air.
Israel is implementing its laser dome. Iran has unveiled laser weaponary. US is installing on destroyers. China is experimenting with using lasers to stop hypersonic cruise missiles by stripping the missile of its protective coating thus causing physics to take over and incinerate at Mach 14+ speeds.
You can also use jammers and EW that force the commercials drone to land, but the range of those is limited and you would need many systems to cover a massive base the size of Parchin or Isafhan airbase.
I think a laser based system while it might have higher upfront cost, in long run it will be cheaper to operate as all you need is power and not a supply of air defense missiles or large caliber ammo.
