Right - it would be impolitic to say this directly.
What you are doing instead is (effectively) calling for the cessation of all military aid. Which would inevitably force the Ukrainians to do just that, shortly enough thereafter.
And saying stuff elsewhere like "it certainly would have been the prudent thing to do for them", referring to the prospect of their capitulating in the early stages of the war.
So at the end of the day - this is precisely the outcome you're lobbying for.
It was very much not the intention of Russia to get into such a fight, they made that clear.
One would have to be absolutely deluded to believe this.
Or more simply - paid to pretend to.
