Guess you wanted to wait to respond till the perfect plan was in place.
The Iranians had other ideas.
The point isn't that the plan was not perfect, but rather that the politicians threw it out, and "winged" it. Political leaders need enough military, and for that matter other non-political, experience to know when they are being given the smoke and mirrors treatment, and when to listen to their experts. The current Israeli leadership, and some of ours, (Rumsfeld was a Navy pilot) don't really meet that requirement.
