What does Gondor have to do with anything?
Er, no. Kubota suggested giving whatever Xykon wanted to him, except what he wanted was the Gate and we all know why that's a bad idea. Plus Kubota wasn't in on the secret, though I wonder if that'd have changed much anyways. Might have changed the minds of some of the nobles, actually, considering Kubota was apparently quite more power-hungry than the others. But it wouldn't have been worth spilling the beans anyways.
