Yes we all know this information.
The war has a higher rate of finishing with destruction of world economy than destruction of Iran's infrastructure. Not just a deal.
The war is already ugly. Iran not only has time, but leverage. This time, I agree with their stance. No more ceasefire. War ends in permanent peace, or continue fighting. No other way to ensure Iran's security.
Which is why US will not want to be sucked into another Vietnam war. USA have a lower threshold for losses despite the might military strength you just mentioned.
