The new intelligence threat about the new Russia anti satellite capability is a nothing burger. Its been known for years in our media and even the russian media.
4 nations already have proven Anti satellite capability, unsurprisingly they also are the top 4 miltary powers USA, China, Russia, India.
The only difference is that Russian one is based in space using either Microwave, Laser or hit to kill from space vs the current norm of the 4 countries which is a hit to kill launched from earth or aircraft.
Several years back it was reported in the media that russian sattelite course corrected and was trailing just above the US spy satellite and they also said that some of those satellites launched a smaller inspection probe.
China already is known to have a land based large laser/microwave/ electronic warfare capability from their desert, they have been testing this on satellites.
They like the USAF also have a space plane that stays in orbit for months both aircrafts missions are still classified.
Elon Musk said SpaceX had to increase their starlink transmission power due to russian electronic warfare.
The chair of intelligence community who sent the memo, has either been leaving under a rock or is using this to to force the house to pass the bill, he was after all seen in Kiev few days back.
