Trump got the assurance of Pakistan that they would not get involved in the inevitable strategic bombing by US, that was obvious from the meetings earlier in week. The US had to move because Israel was possibly days away from using a nuclear weapon on Iran anyway. US also already had the backing of the Emirates, who despise Iran. So Iran I would say may have China sending them missiles. May have Russian rhetoric behind them but ultimately, the regime is on their own now.
The realistic concern would now be the closure of the Strait of Hormuz, it wouldnt take Iran much and Ive experience of delays in issues with that shipping highway its not good, so to close it would be a huge issue in shipping.
I think Iran will just continue targeting and firing at Israel, may be target a US base, but ultimately the regime cant win. Its a dangerous situation when the regime is of a ideological mindset that death is the ultimate victory in the with or without victory in life. Most of the Iranian people, from what I can perceive from people I know, despise their rulers but the IRG are ruthlessly clamping down on any dissidence in the country at present, so a rise up by the people is next to impossible without significant help on the ground.
I dont think the attack certainly on the deeper nuclear facility located under the mountain, would have achieved anything significant.
Nobody can really predict whats going to happen now. I think Irans regime will fall, they have nobody to turn to and China will not enter itself in to a war, it has no interest in projecting outside of its region but it may continue to supply weapons to Iran for the time being. Russia will do nothing. Sleeper cells could be an issue, has been a huge concern for years. Outside of this, I think the regime will be killed off and perhaps it will get to a lower down person who wants to do a deal.
My biggest fear is that the fate of Iran, is that of Libya, Syria and so on. Places that were amazing, rich in culture and history, lovely people and its smashed to pieces and wiped out in waring militants killing men, women and children and killing each other, which is all thats going on in Libya now and I think quite clearly, also in Syria exactly as predicted. That to me is awful, the Persians do not deserve that, no people on this Earth deserves that, but its always the people that suffer the madness of religious zealots and psychopathic leaders.
As for some huge conflict being sparked from this, I don't see this happening at all.
Huge sympathies to the poor people caught up in this.
