Iraq was arguably the most successful military campaign anywhere, ever. The remit given to miliary commanders was regime change by military force and the resulting effort was a masterpiece of the effective use of precision military effects. The problem of course was the lack of a coherent executable plan for the day after. Defeating Iran militarily is the easy part, managing the fall out is a a whole different magnitude of hard. The region is at a tipping point and use of force decisions by Israel and the USA will have lasting consequences, but the status quo is not sustainable. A regional war is IMO inevitable and Iran will be decisively defeated, lets just hope there is a plan for a sustainable peace after the kinetic effects are over.
