I agree totally with what Finwe says.

And it is from his idea that my question arises. Since Nenya was used for defensive purposes, among others, lets consider the posibility that the protective "girdle" that Galadriel wove around Lothlorien could be expanded towards Dol Guldur when the White Council attacked.

If Galadriel's girdle was used for repelling all kinds of evil (i.e. the orcs, the Nazgul, etc) imagine the scenario were Galadriel's power was strenghtened with the aid of the other known members of the Council (Gandalf, Saruman, Elrond)to expand the girdle towards the south region of Mirkwood, in order to kick out the Necromancer and his allies. I know its a big maybe, but its a possibility.

Otherwise, would the White Council risk open war against Dol Guldur? And by that I mean sending troops against the fortress (elves from Lorien, Rivendell and Thranduil's realm... can't think of another force being sent there) when they know that Sauron lurks in the fortress and that his sorcery and his orcs (and other fell creatures) are all around it? Wouldn't you attack Dol Guldur, first, from a distance (Galadriel's magic, fueled by the others, from Caras Galadhon) to undo Sauron's craft protecting his fortress, and then send elves to kick out whatever creatures remained behind?

I think it would be a possibility...
