>our Russian friends hated the idea because they can't into maintenance. And so, the idea never really worked out for them as well as it should have.

But it worked well. MiG-23 was very successful long-living plane, it's late fighter-bomber variant (MiG-27) was decommissioned not because it was bad, but for other reasons (simply economics after USSR collapse). Late versions (MLD) were especially good for plane of that age they could even fly without pilot like in Belgium in 1989

Su-24 was also pretty successful too, it is phased out just because of age. Tu-160 still active and will serve for long.
