Uh, it might be a good idea in this case, but maybe we should wait and see if poll fraud actually happened. The first priority is to demand that foreign media be allowed to cover the protests in Iran.
But don't forget, we're almost universally hated because we "try and replace the regime" when we don't like what they're doing, including in Iran in 1954.
Unfortunately, though, you can pretty much rest assured that the U.S. will only overthrow Ahmadinejad if there's some private interest behind it. Be weary of any overthrow in the name of democracy.
