If 40+ years ago NRO had meters resolution imagine what they could have today...
> A perfect 2.4-meter mirror observing in the visual (500 nm) would have a diffraction limited resolution of around 0.05 arcsec, which from an orbital altitude of 250 km would correspond to a ground sample distance of 0.06 m (6 cm, 2.4 inches). Operational resolution should be worse due to effects of the atmospheric turbulence.[24] Astronomer Clifford Stoll estimates that such a telescope could resolve up to "a couple inches. Not quite good enough to recognize a face".[25]
Such a thing would be used by both sides in urban conflicts to "see round corners" and track targets.
