We have had this capability for many years now.
One of the greatest legacies of "Star Wars" is that most people never understood it. And while most actually involved in the R&D aspect knew it would take decades to make anything concrete from it, it was pushed as something which would happen in the next few years after it was announced.
And the Soviets spent themselves bankrupt trying to catch up, and achieve things that we knew were impossible.
As they spent billions of rubles trying to increase and improve their LASER capabilities, we put all of our effort into things that actually got results. GPS, a new generation of digital communications, small aperture satellite communications, and kinetic kill vehicles.
We knew since 1991 that Star Wars would succeed, we saw that in the Gulf War with the PATRIOT missile. And that was with a very preliminary "proof of concept" code that was only designed for test use, with missiles that were never designed to take out other missiles.
At that point, it was only a matter of upsizing it into the SM2 and SM3 series missiles of today. And we have actually had this capability for over 15 years now.
I actually had a conversation with somebody about this over a year ago. He claimed that Star Wars was a boondoggle, and never accomplished anything. I pointed out THAAD, PATRIOT, SM2 and SM3 and he admitted he had only heard of one of those. But he still insisted SDI was a waste of money and accomplished nothing.
