Well at present Iran has made it perfectly clear:
1. They reserve the right to strike gulf nations hosting US bases
2. They wish to exert control over the SOH
3. They are not in the mood to re-open negotiations, in fact one of the most prominent and influential clerics inside Iran [Alireza Arafi] has stated pretty much this - no negotiations.
Iran will likely want to drag this out for the US to hurt them economically, but its difficult to see if this strategy will pay off - the winds are shifting and whilst the strategic needle still hasn't moved in favor of Washington, on the diplomatic front seems Washington has secured quite a few W's - this is evident from the fiery speeches made by the UK/France and German representatives to the UNSC 4 days ago.
Iran still has trump cards (pardon the pun) the Bab-el-Mandeb being one and their partners in Iraq and Lebanon being the other. Although seems they may end up losing their support base inside Iraq (watch this space).
There are renewed whispers about the US taking an Island or two - this may or may not happen, too early to tell. One thing is clear; the US have shifted their target selection from their previous jaunt into the region.
