What if Smaug the dragon lived?

[Elu Ancalime]

The main thing I think of is

Dragon-fire, and savage swords in Eriador, night in Rivendell

He would have impacted the war in the north much. Although Minas Tirith still would probably have outlasted the Battle of the Pellenor, Dol Guldur might have succeded in destroying Lorien (thinkabout it-dragon fire and forest, there would have been a difference) and the Wilderland would be taken. Sauron would till be defeated, and the orc armies would...whatever....but since dragons are independent, I think Smaug might have settled down somewhere in the Hithiglir, maybe some hole into Moria? Which might have made for another book....
