Depends what you define as winning. We defeated their military quickly and with few losses. It's "nation building" that was so messy.
Same would be true here.
This. It would be a disaster and quite possibly ruin the dollar.3 weeks to beat their armed forces but 10 years+ to beat the 'insurgency'
honestly tho, military i think even less then 3 weeks. 3days - 1 week of bombing bridges, power lines, water lines, roads, tanks, government buildings, command and control.
week 2, military tanks will be rolling in the streets of Tehran.
of course there would have to be months of troops build up in the area and planning and the most painful part of fighting a war, is logistics.
as for the "insurgency" i think that would be a long/nightmare of a problem.
China might dump their dollars.
Russia and China will use their nuke option to stop an attack on Iran. They will not let another oil nation fall into the hands of the USA. WW3 is the only outcome of attacking Iran and there will be no winners except the elite who planned the whole thing.
They haven't figured out how to stop every last shell from hitting Saudi Arabia yet...
If Iran knew anything they wouldn't even begin to fight back until 6 months after the invasion.
In every official war game that I am aware of, it hasn't ended pretty. One such war game, called Millennium Challenger, was carried out in 2002 by the Pentagon. It had to be canceled before it ended because the Iranian side was in the process of defeating the US Navy using asymmetrical and conventional warfare techniques.

Iran is believed to have more than 5,000 mines available, many of modern design and exceedingly difficult to detect, sweep, and disarm. The Iranian Navy has also become adept at small-boat swarming tactics, in which large numbers of light vessels attack larger warships in what have been described as suicide runs.
Advanced weaponry from Russia and China as well as Iran’s asymmetrical warfare capability help maintain some deterrence. Iran has Chinese sea-skimmer models and has also developed its own variants.
