Certainly gandalf takes a much more direct role by actively engaging the nazgul, goblins and balrog, but his role is deliberately indirect to the grand narrative.
Actually, in order to match what Biden is doing, Gandalf would have to be supplying the armies of Saruman and/or Sauron with a significant portion of their swords and siege weapons, all the while pretending to tell Sauron and Saruman to please don’t kill so many people.
Simply by amount of arms, I like that, but it’s dependent on gandalf and sauron having been friends for decades and coming to each other’s military aid dozens of times over their relationship because they share a mutual interest in modes of government, and gandalf being the short-term inheritor of this extremely consistent lifetime mutual dependence and support.
