Stopping a multi-thousands warhead attack by a country with MIRVs and decoys, was, is, and always will be, technically and fiscally impossible. It will always be cheaper for the adversary to just build more missiles than for the defense to stop them. Star Wars would not have worked to stop most of an attack by even the current Russian nuclear forces if we'd spent the entire GDP of the US every year for 20 years on the project.
Using the test today as "proof" that Star Wars would have worked is like saying someone wearing a kevlar vest surviving being shot by a single .22 round is "proof" that the vest would ALSO protect the person if they were surrounded by a dozen guys with .50 machine guns each blowing through a thousand rounds.
Nope, but protecting the most strategic asset would have been a deterrent. It made a retaliation-free first strike real possibility.
You guard only a select number of missile silos, so that you can ALWAYS launch.
However, I disagree with impossible. Once the laser intercept is perfected, it is entirely possible to target massive numbers of incoming. And that makes both survivability and retaliation a real probability.
Correction:
...but our regulatory debt regime keeps nearly everything built by our contractors overly expensive. [Little haste there on my part.]
You appear to be in desperate need of basic education. Cheers, and lay off the democrat bullshots.

But, do they have multi-thousands of warheads?

I believe Tesla would heartily disagree as he had solved this issue (war prevention) in the early 1900’s.
We as a society are very far behind where we should be mostly due to petty jealousies and greed.
