I don't know about Poland (would they really want a "dirty" bomb detonated so close to their own territory?), But I can easily see the CIA and MI5 being involved. There was a lot of scuttlebutt in 2020 about the Deep State threatening to explode a dirty bomb in an American city if DJT and the American military were to forcibly prevent Old Joe from taking up residence in the White House.
