(Answer to question from Sputnik)
I can’t see any reason for Putin bothering unless it be curiosity to see for himself Biden’s state of mind. I do not expect anything to change — the Biden/Harris Administration is packed full of the people who fully embrace the numerous Russia conspiracy theories, invented many of them and who made US-Russia relations impossible.
As to Nordstream, Washington was trying to placate Berlin; it’s still trying to stop the pipeline.
Biden wants to show himself statesmanlike, important and in charge; Putin doesn’t have to.
The only possible interest is to bet whether Putin walks out when Biden starts up with the customary accusations.
