I seriously can't wait for this technology.

It can be purely defensive, and shoot down all aerial attacks - drones, etc. over your country's airspace.

So... no wild weasel, no successful air raids, etc. We're back to ground invasions, and frankly, a country can defend against those a lot easier.

And it also means countries not lobbing missiles at each other, and at oil fields and igniting them, or destroying shipping etc.
