If Russian GNSS receivers wasn't affected they wouldn't need fiber optic drones, Ukraine is jamming both the small and large drones. Russia have both their own Kometa system to try to filter out the jamming signals, and plenty of Chinese tech as well.

To be fair, USA also could not defend their allies and their bases, and didn't move the frontline in Iran as well. And if Iran buys a submarine capable to launch missiles from a friendly country the situation might get worse.
