What To Do About Iran

So my friends the usual Conservative suspects are talking about the leaked Gates memo in which he tells the President the US has no plan for dealing with Iran. We're all outraged and sarcastic.

But I still haven't heard (that post is from Feb.) anyone else's plan for preventing Iran from getting nukes. What is there to do except let the Israelis bomb their reactors? I am really asking, because it doesn't seem that Bush had much of a plan, either.
