All out war just isn’t on the cards, look at it this way, Iran & Iraq had a bitterly fought and bloody contest over 8 years which bar the shouting ended in a draw.
The U.S. military effectively rolled over the Iraqi army in less than a month, Iran watched and knows this only too well.
They seem the masters of pushing the U.S. to the brink without getting a full retaliation, I do fear though that there will be a follow up attack by an Iranian backed 3rd party which will get an extreme response from Trump, for his many many many flaws I don’t think any plausible deniability such attacks in the past have held will wash with him, and that’s something I really don’t want to see.
For now, it’s calming down, but I don’t think we’ve seen the last of this by any stretch.
I just pray Iran don’t think they can carry on as before with Trump as the commander in chief, I suspect they might but pray they don’t.
