Breech of Contract
Simple question:
Did Gandalf breech his contract, and if he did, was it appropriate given the context.
LotR The Two Towers pg. 117
"... Did you find them, and are they safe?"
"No, I did not find them,' said Gandalf. 'There was a darkness over the valleys of the Emyn Muil, and I did not know of their captivity, until the Eagle told me.'
'The eagle!' said Legolas. ' I have seen an eagle high and far off; the last time was three days ago, above the Emyn Muil.'
'Yes.' said Galdalf, 'that was Gwaihir the Windlord, who rescued me from Orthanc. I sent him before me to watch the river and gather tidings. His sight is keen, but he cannot see all that passes under hill and tree. Some things he has seen, and others I have seen myself. The Ring now has passed beyond my help, or the help of any of the Company that set out from Rivendell. Very nearly it was revealed to the Enemy, but it escaped. I had some part in that; for I sat in a high place, and I strove with the Dark Tower; and the Shadow passed. Then I was weary, very weary; and I walked long in dark thought.'
Was this contest with Sauron a breech of his commandment not to confront the Dark Tower with brute force? Was it acceptable, even to save the ring?
This is a fairly simple case, so lets expand the question. Would the Valar have liberated Middle Earth from domination by Sauron? If the west had fallen, would they have cast him out like they did to Morgoth? How far does the edict of nonintervention go?
