There's no free lunch in orbit. If it dips into the atmosphere enough for control surfaces to bite then it has to boost back up again to avoid orbital decay. Either way it can't possibly carry enough fuel to do much of that.

It doesn’t have to return to orbit. Switching from an orbital trajectory to a parabolic intercept path would be feasible, and open valuable tactical space.
As long as it can travel back to a US-friendly airfield. Which is probably a large number around the world although few which would support classified vehicles?
