Right. I was assuming/implying a lot by saying, "if you had the controls." In the hypothetical where you have complete control of the ISS (despite manual overrides, et al), you'd still have a very hard time hitting a specific target on Earth. You could crash the thing fairly easily though. That's all I meant to say; I understand that this isn't a practical reality.
Yup, I understood. I was just adding a thought about how it was even more impractical than your comment suggested. Wasn't arguing against your point itself.
