You'd have to be either a liar or a fool to publicly admit that you've deciphered something about your opponent's secret capabilities. The allies didn't go bragging to the Nazis every time that they broke the enigma machine.
I used to think that I had some additional insight, hailing from a country neighbouring Russia, but it takes being born on former soviet territory to fully understand their line of thinking.
It's not that it's particularly sophisticated - just utterly foreign to anyone even west-adjacent.
USSR/Russia has always loudly overstated the capabilities of its military and military hardware.
The US tends to stay mum about the capabilities of its hardware and when it talks about them, it tends to understate.
Even when the F-22 shot down that Chinese balloon (a hilarious use of cutting-edge air power) it was more impressive than it might have seemed at first glance. For years the claimed ceiling of the F-22 was 50,000 feet. But then they mentioned that it shot the balloon down from a height of 58,000 feet. Now the Wikipedia article (after years of edit fights) seems to have settled on 65,000 feel and the official USAF page says "above 50,000 feet". Maybe a trivial example but kind of representative.
(Don't get me wrong, the US "flexes" military might in other gaudy ways. I'm not saying we are humble and Russia is not. It's just funny how the two countries go about it differently....)
We're basically using Ukraine to dispose of an outdated system ("In 2007, the U.S. Army terminated the ATACMS program due to cost, ending the ability to replenish stocks"; https://en.wikipedia.org/wiki/MGM-140_ATACMS) we intend to deprecate.
The https://en.wikipedia.org/wiki/Precision_Strike_Missile is intended to replace it and has seen its first deliveries last year.
There's little indication they're worthless, and an article breathlessly citing someone saying "This is a signal to the whole world, not just the West, that Western weapons are no match for Russian arms" is not a change to that.
