I don't believe it for a second. Why would they change after 5 years? The current White House defines "fighting back" as a couple of short statements at the daily White House briefing.
Don't expect anything exciting or effective.
They would change after five years because they have just been hit in the forehead with a 2 x 4. The Libby indictment and this Rule 21 stunt would be that 2 x 4.
