The alternative for Special K is a tow north of Siberia- with the receding polar ice, that's at least feasible now in the warmer seasons. Still dangerous, but might be easier than hauling her all the way around.
...that said, yeah, with the issues she's had in terms of maintenance, damage, and ineffectiveness (as previously noted, her planes were more useful from land bases than from the ship), it might nto be a bad idea to either scrap her or offer her 'as-is' to anyone interested. Bring your own tugboat, no lowballers, we know what we're selling, no trades. ;)
(And yes, Su-57 is a lovely airplane that makes the F-35 program look like smooth sailing. I'd be surprised if they ever go into large-scale production at this point.)
