They all have sensed that major work is done already by the US.
"Major work" is not done by the US yet. Far from it, Iran last night displayed it still have the munitions and capability to launch them.
Yes, they have taken a hammering on the coastline, but Iran is a huge country, there are pundits talking about capturing Abu Musa and the Thob Islands... Okay fine, they capture them, let's say for arguments sake, who is going to hold and defend them?
This war has always been about containment, so occupation and control of territory make no strategic sense, unless the US wants to be dragged into another loop of "forever wars". Can the US take the Islands?
YES, they can, will there be appetite in the US for long term boots on the ground or
"Korea style police action"? Not so sure!
A majority of American's polled by IPSOS do believe that the war is now headed into a territory where it may become long and protracted:
The Republicans have just pushed through the $95bn budget plan which includes
$60bn for defence, $13bn for intelligence, and $12bn for agriculture, as US farmers face higher fuel and fertiliser costs during the war.
These are all signals that as far as the current US administration go, they are willing to dig in their heels. The strikes on Iran are about degrading its capability yes, but also to see who will blink first.
The US has already spent >100 billion USD on the war.
The analysis and theory crafting of the US capturing the three Islands are still discounting the crisis that would hit international shipping and energy sectors if the bab-el-mandeb were to be shut or compromised in any fashion, what pressure the Houthi's can exert there remains to be seen as we know that area has a large NATO naval presence.
What about regional countries? What if any role will they play if the conflict expands?
NATO and US aircraft have been tracked at increasing frequency travelling to and from Egypt:
This time its going to be NATO + US. Its already started as NATO air refuelers are getting more active lately.
Those multi-national refuelers you are seeing are in a support role only, what role if any NATO will play is yet to be seen, but it's important to keep an eye on this.
Yes
This time, they are severely degrading Iran's abilities and will seek a new agreement where Iran would not be offered anything substantial.
Will have to see what happens, things are still much to fluid.
The last MoU was considered a victory for Iran.
Yes and No.
But even then some hardliner Iranians were not happy, now all hardliner Iranians should be very happy they got the resumed war what they wanted.
How the Iranian leadership choose to conduct this war is their own remit.
