Iran needs to hunker down and work through this patiently and absorb some pain.
They were surprised by Iraq too (aided by US/European largess) but they came around.
From the reports about the destruction of Iranian missile launchers, I am sure some are being lost, however keep in mind what Scott Ritter said about US efforts to take out Iraqi SCUDs. He said our success rate was less than 10%. And this was with USAF/USN/RAF/French assets constantly covering the entire length and breadth of Iraqi airspace 24x7. This is not the case with Israel. So success rates of the Israelis will not be that much higher despite the propaganda.
If Iranians are smart, they are shooting and scooting and using decoys in large numbers to preserve their strike capability.
Second, the issue with Fordow is that if the US gets involved, they won't strike it once, they will probably drop multiple bombs at the same point of impact so the boring goes deeper with each bomb till it hits the enrichment core. So in the case of US involvement, Fordow will probably be neutralized.
However, Iran will probably react in the strait and at other US bases. A regime change cannot take place for as long as the US/Israeli side puts boots on the ground. So some form of the current Iranian structure will continue.
Last, I am taken aback by the number of traitors inside of Iran. The way they have backstabbed their own country/nation is mind-boggling even more than what happened in Lebanon because in Lebanon, there are other sects always working at cross-purposes from the Shia'a. Here in Iran, this is really surprising. All lessons to observe and learn from.
