Had Smaug Lived to See LOTR...

[blantyr]

I'm figuring the one thing harder to herd than cats might be dragons. While Morgoth once commanded them to fight as a team, have any of them acted as part of a team since?

I shouldn't really second guess Gandalf's opinion, but I don't see Smaug going too far from his nice golden bed, and I can't see him sitting idle when the darkness comes. He'd do something, but I'm not sure what.

There would be risk if he'd gone against the elves of either Mirkwood or Lorien. The elves have the eyes and the archery skill. Smaug was arrogant enough to go after them anyway. I've no reason to expect Smaug would select Fangorn as a target, but he'd be one enemy a forest of hurons wouldn't want to see.
