The GRU operation against Burisma, linked to Joe Biden’s son Hunter, again entangles Moscow in domestic U.S. politics.

Imagine for one moment you are Vladimir Putin. Sitting on the desk in front of you is a file labeled “Trump, Donald.” Inside is a stack of documents your spy agencies have collected that prove that Trump took part in embarrassing or illegal activities.
