While there is no doubt that the US could inflict massive damage on Iranian nuclear sites, critical infrastructure and oil production facilities; there is also no doubt that the US would not prevail in a protracted conflict with Iran.

For some reason, the author does not recognise that US could nuke (around 16 sites as told) Iran. For that matter Israeli 'Sampson option' could be at play.
