[Inderjit Sanghera]

I think that Boromir would have went to Minas Tirith, thus taking the ring to Denethor. He might have given the ring to his father, but I doubt it. Meanwhile, without the arousing of Theoden and the Ents, Rohan would’ve been taken. Denethor, or Boromir would have marched to Mordor, or maybe on the fields of Pelennor and he would have been defeated, since Sauron would have sent a stronger force then he did in Pelennor. They would have captured Denethor/Boromir and brought him to Sauron, who would have taken the ring off him. Rohan was destroyed, as was Gondor and Mirkwood and Erebor would’ve fallen. With the humans down and out, Sauron, with the one ring, would’ve shifted his attention to Lorien and Rivendell. They would’ve been taken and everyone would’ve died, including the fellowship and Gandalf.
