Congress wants to keep the A-10 Warthog flying even though the Air Force desperately wants to be rid of it because it's a good jobs program, there are considerations outside of battlefield prowess that go into their thinking. Not to completely dismiss their opinions because they probably have more information than we do, but their world is not warfare.

Even giving the Russians every capability that they claim to have, it is questionable if they can even keep producing much of the high end of their technology with the sanctions leveled against them. Without Western components they are unable to manufacture a decent range of their good stuff.
