RINO snorts in #280 above:
"Anything short of a knockout of the Iranian regime is failure. Winning this fight on points means that the Iranian regime lives to fight again."You're 100% correct, of course.
That means "regime change", or even moreso, the
obliteration of the regime as it exists now.
As I posted yesterday, this is going to require a scene similar to this one:

NOTHING LESS can or will be considered "victory".
And the surrender must be followed by "an occupation" of sorts -- to determine that all nuclear facilities have been discovered, and cleaned out properly.
The occupation might also require a short rule by the U.S. Military, a la Japan post WW2.
With the subsequent selection of new "rulers" after sufficient vetting.
If you want to WIN, then you must accept the responsibilites and take proper actions AFTER you have vanquished the enemy, as above. As we did in both Europe and Japan when the war was over.
Let the Shah's son come back, perhaps as a figurehead. But MAKE IT CLEAR to him that his rule will be limited in time and restrained in force. And that any abrogation of such will result in a withdrawal of western support.
That's my opinion and I ain't changin' it.
