I think that would be colossal mistake. It would make Iraq look like Grenada. Of all the countries in the Mid East that have any chance of becoming a democracy, its Iran. As someone else pointed out, the Little Man is sick and is not especially loved. Let nature takes its course and in a year or three we will be dealing with a new, probably more moderate, regime. A unilateral attack by us or Israel would be a disaster.
Agree but it'll be Israel with the first response. As you know these things are "sold" in bits and pieces.
