It was part of the essential deceit of
the Ring to fill minds with imaginations of supreme power. But this the Great had well considered and had rejected, as seen in
Elrond's words at the Council.
Galadriel's rejection of the temptation was founded upon previous thought and resolve. In any case Elrond ir Galadriel would have proceeded in the policy now adopted by
Sauron: they would have built up an empire with great and absolutely subserviant generals and
armies and engines of war, until they could challenge Sauron and destroy him by force. Confrontation of Sauron alone, unaided, self to self was not contemplated. One can imagine the scene in which
Gandalf, say, was placed in such a position. It would be a delicate ballance. On one side the true allegiance of the Ring to Sauron; on the other superior strength because Sauron was not actually in possession, and perhaps aslo because he was weakened by long corrupetion and expendature of will in dominating inferiors. If Gandalf proved the victor, the result would have been for Sauron the same as the destruction of the Ring; for him it woudl have been destroyed, taken from him for ever. But the Ring and all its works would have endoured. It would have been
the master in the end.
