> even the resolution of their images are classified

Yeah, but physics isn't. Good resolution requires large mirrors. Large mirrors require large satellites. These aren't cubesats we're talking about; optical American spy satellites have 2.4 meter wide mirrors and are more than 10 meters long. The only non-US/Chinese/Russian rocket that can launch such a satellite in principle is the Ariane 5, but AFAIK they don't fly that to polar orbits.

In any case, not many people have the equipment laying around to make such large mirrors, or the expertise, or a stockpile of such mirrors. Russia likely has all three, or certainly once did.
